The FAA is superseding Airworthiness Directive (AD) 2019-02- 03, which applied to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2019-02-03 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. This AD retains the requirements of AD 2019-02-03 and requires incorporation of an airworthiness limitation that applies only to certain airplanes. This AD also requires replacing or modifying certain engine fire control panels, which terminates the revised airworthiness limitation added in this final rule when a certain condition is met. Since the FAA issued AD 2019-02-03, the manufacturer has developed a new fire handle design that will eliminate the need for the airworthiness limitations required by AD 2019-02-03. The FAA is issuing this AD to address the unsafe condition on these products.

AD 93-14-19 required inspections for disbonding of the trailing edge wedge of the leading edge slat; and repair, if necessary. We issued AD 93-14-19 to prevent the loss of a trailing edge wedge, which could result in reduced maneuver margins, reduced speed margins to stall, and unexpected roll before stall warning, all of which would adversely affect the controllability of the airplane. Since we issued AD 93-14-19, an updated stability and control analysis showed that the worst-case scenario of a trailing edge wedge disbond in-flight would not adversely affect the controllability of the airplane.

We are superseding Airworthiness Directive (AD) 97-07-14, for certain Airbus Model A320-111, -211, and -231 airplanes. AD 97-07-14 required modification of an area on the front spar of the wing center section by installing shims and new fasteners to reinforce pressure floor fittings. This new AD continues to require modifying the rib flange on the front spar of the wing center section by installing shims and new fasteners to reinforce pressure floor fittings; and requires repetitive high frequency eddy current inspections for cracking of the radius of the rib flanges and vertical stiffener at frame 36, a rototest inspection for cracking of the fastener holes of the rib flanges, repair if needed, and adding additional airplanes to the applicability. This AD was prompted by the need for repetitive inspections on airplanes on which the modification of the rib flange on the front spar of the wing center section has been done. We are issuing this AD to prevent fatigue cracking on the rib flange area of the front spar of the wing center section, which can reduce the structural integrity of fuselage frame 36 and the wing center section.

We are superseding Airworthiness Directive (AD) 2009-18-18 for certain ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and ATR72 airplanes. AD 2009-18-18 required repetitive inspections for damage and absence of repair of the cockpit forward side windows, and replacement if necessary. This new AD requires repetitive detailed inspections of the cockpit forward side window for damage and discrepancies; and replacement if necessary. Replacing both cockpit forward side windows with approved windows terminates the repetitive detailed inspections. This new AD also expands the applicability of AD 2009-18-18. The actions required by AD 2009-18-18 are not required by this AD. This AD was prompted by reports of a cockpit forward right- hand side blow out during flight. We are issuing this AD to detect and correct air/water leakage of the cockpit forward side window, which could lead to rapid cabin decompression, resulting in loss of control of the airplane.

Airworthiness Directives; Airbus Airplanes · published 18 Sep 2012
We are superseding an existing airworthiness directive (AD) for all Airbus Model A330-243, -341, -342 and -343 airplanes. That AD currently requires modifying certain cowl assemblies of the left- and right-hand thrust reversers. This new AD requires removing certain C- duct assemblies of the left- and right-hand thrust reversers from service at certain designated life limits, and also adds airplanes to the applicability. This AD was prompted by new life limits on certain thrust reverser C-duct assemblies. We are issuing this AD to prevent fatigue cracking of the hinges integrated into the 12 o'clock beam of the thrust reversers, which could result in separation of a thrust reverser from the airplane, and consequent reduced controllability of the airplane.

Airworthiness Directives; Goodyear Aviation Tires · published 29 Aug 2012
We are adopting a new airworthiness directive (AD) for Goodyear Aviation Tires, part number 299K63-1 (Brazilian made new tires only), installed on various transport category airplanes, including but not limited to Bombardier, Inc. Model CL-600-2B19 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as tire tread separations and tread-area bulges on the main landing gear tires due to low adhesion in the tread shoulder area. The unsafe condition is specific to Brazilian produced new tires, size H29x9.0-15, only; retread tires are not affected by this AD. This condition, if not detected and corrected, could cause the main landing gear tires to fail during takeoff or landing. The failure may cause damage to the airplane structure, flaps, engine, and wheel well and result in reduced controllability of the airplane. We are issuing this AD to require actions to address the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: An investigation into the loss of a TRU during landing has revealed that this incident was preceded by the detachment of the TRUs fixed structure front ring rivet lines on the rear flange. It was concluded that the loss of rivet lines was directly associated with a previous translating cowl gearbox stubshaft fracture and the subsequent repair of the fixed structure to Engine Manual repair No. FRS5887. This repair instructs the replacement of the damaged section of the structure but does not require the rivets adjacent to the repair to be replaced although latest analysis has shown that the rivets may have weakened as a result of a translating cowl gearboxstubshaft failure. We are issuing this AD to prevent failure of the attachment rivets resulting in loss of engine structural integrity, which may result in release of the thrust reverser unit from the engine.

We are adopting a new airworthiness directive (AD) to supersede Airworthiness Directive (AD) 2006-17-01, AD 2006-15-07, AD 2000-02-25, and AD 97-25-02, which applies to certain Mitsubishi Heavy Industries, Ltd. (MHI) various Models MU-2B airplanes. An FAA MU-2B safety evaluation resulted in the standardization of the MU-2B specific training and the FAA-accepted pilot operating checklists through a special Federal aviation regulation (SFAR). MHI revised the airplane flight manuals (AFMs) to align them with the information in that training and the checklists. In addition, incorporating all AFM revisions up to and including this latest AFM revision will incorporate all AFM compliance actions required by the four above-mentioned ADs. This AD would retain from AD 2006-17-01 the inspection of the engine torque indication system and possible recalibration of the torque pressure transducers and would require incorporating all revisions up to and including the latest revisions of the AFM. We are issuing this AD to correct inconsistencies in critical operating procedures between the MU-2B specific training, the FAA-accepted pilot operating checklists, and the AFMs, which, if not corrected, could result in the pilot inadvertently taking inappropriate actions in critical operating conditions.

The FAA is superseding an existing airworthiness directive (AD) that applies to certain Bombardier Model DHC-8-400 series airplanes. The existing AD currently requires revising the Limitations section of the airplane flight manual (AFM) to include procedures for pulling the "HYD PWR XFER'' circuit breaker in the event of the loss of all hydraulic fluid in the No. 1 or No. 2 hydraulic system. This AD requires a revision to the AFM to include additional procedures for ensuring that the "PTU CNTRL'' switch is Normal, the "PTU CNTRL ON'' advisory light is out, and the "HYD PWR XFER'' circuit breaker is pulled in the event of the illumination of the "2 HYD ISO VALVE'' caution light. This AD resulted from low No. 2 hydraulic pressure in-flight, which caused the power transfer unit to overspeed, and the fluid flow within the No. 1 hydraulic system to increase. We are issuing this AD to prevent possible loss of both the No. 1 and No. 2 hydraulic systems, resulting in the potential loss of several functions essential for safe flight and landing of the airplane. DATES: This AD becomes effective September 2, 2008. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of September 2, 2008.

This amendment adopts a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-76A, B, and C helicopters that requires inspecting each installed Woodward HRT (formerly HR Textron) main rotor servo actuator (servo actuator) for a high rate of leakage and replacing each affected servo actuator with a servo actuator containing a newly re-designed servo actuator piston. This amendment is prompted by a National Transportation Safety Board (NTSB) Safety Recommendation issued in response to an accident involving a Model S-76C helicopter. In the NTSB Safety Recommendation, the performance of a servo actuator piston upon reaching 3,000 hours time-in-service (TIS) was questioned as a result of piston head seal leakage and piston head plasma spray flaking. The actions specified by this AD are intended to prevent degraded servo actuator performance as a result of piston head seal leaking and plasma spray flaking, which could result in subsequent loss of control of the helicopter.

We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: * * * [T]he FAA has published SFAR 88 (Special Federal Aviation Regulation 88). * * * Under this regulation, all holders of type certificates for passenger transport aeroplane * * * are required to conduct a design review against explosion risks. One of the consequences of the Airbus design review is the modification of the fuel pump wiring to provide protection against chafing of the fuel pump cables. This condition, if not corrected, could generate short circuits leading to fuel pump failure and arcing. These could become a potential ignition source inside the fuel tank which, in combination with flammable fuel vapours (if present), could result in a fuel tank explosion and consequent loss of the aeroplane. To address this unsafe condition, EASA [European Aviation Safety Agency] issued AD 2007-0066 that required this modification [of the fuel pump against short circuit] in accordance with Airbus Service Bulletin (SB) A300-24-0103 Revision 01. Airbus subsequently introduced an additional modification of the electrical wiring of the outer fuel pump and the landing lights of the left (LH) and the right (RH) side in Revision 02 of the SB A300-24-0103, leading to the issuance of EASA AD 2008-0188 which superseded EASA AD 2007-0066 and required the additional work. More recently, Airbus introduced some additional protection to routes 1P and 2P harnesses in zone 571 and 671 of the aeroplane. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.

This airworthiness directive (AD) supersedes two existing ADs. One AD applies to certain Airbus Model A310-200 and -300 series airplanes. That AD currently requires repetitive inspections for cracking of the flap transmission shafts, and replacement of the transmission shafts if necessary. That AD also provides an optional terminating action for the repetitive inspections. The other existing AD applies to all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600 series airplanes); and Model A310-200 and -300 series airplanes. That AD currently requires a one-time inspection of the trimmable horizontal stabilizer actuator (THSA), corrective actions if necessary, and follow-on repetitive tasks. This new AD also requires revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness to incorporate new limitations and maintenance tasks for aging systems maintenance. ThisAD results from the manufacturer's determination that life limitations and maintenance tasks are necessary to ensure continued operational safety of the affected airplanes. We are issuing this AD to prevent reduced structural integrity of these airplanes due to the failure of system components. DATES: This AD becomes effective April 28, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of April 28, 2009.

We are superseding an existing airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: A complete loss of both ignition systems occurred on a DHC-3 Otter when the lock wire hole in the ignition connector plug on the firewall broke out, allowing the plug to vibrate loose. A maintenance safety feature grounds out both magneto systems through a spring-loaded safety pin incorporated into the Cannon plug. The DHC-2 system is similar in design. Subsequent to the issuance of AD CF-2001-36 a complete loss of both ignition systems occurred on a DHC-2 Beaver resulting in engine failure and subsequent forced approach and landing. Investigation by the Transportation Safety Board determined the internal failure of the magneto firewall connectorresulted in both magneto "P'' leads shorting to ground. A maintenance "safety'' feature through a spring-loaded safety pin incorporated in the firewall connector on many DHC-2 aircraft grounds out both magneto systems when the connector is disconnected. This connector type is readily identified when disconnected by the existence of three internal pins on the firewall and magneto harness side, one of which is shorted directly to ground. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective July 23, 2008. On July 23, 2008, the Director of the Federal Register approved the incorporation by reference of Viking DHC-2 Beaver Service Bulletin Number V2/0001, dated June 27, 2007; and Viking DHC-3 Otter Service Bulletin Number V3/0001, dated June 27, 2007, listed in this AD.

The FAA is superseding an existing airworthiness directive (AD), which applies to certain Boeing Model 767-200, -300, and -300F series airplanes. That AD currently requires reworking the surface of the ground stud bracket of the left and right transformer rectifier units (TRUs) and the airplane structure mounting surface, and measuring the resistance from the bracket to the structure and the ground lugs to the bracket using a bonding meter. This new AD revises the applicability of the existing AD to include additional airplanes and requires, among other actions, installation of a new ground stud bracket using faying surface bonding. This AD results from a report of loss of all direct current (DC) power generation during a flight, due to inadequate electrical ground path between the ground bracket of the TRUs/main battery charger (MBC) and the structure. We are issuing this AD to prevent depletion of the main battery while in flight, resulting from the loss of both TRUs and theMBC, and consequent loss of all DC power, which could impact the safe flight and landing of the airplane due to the loss of function or malfunction of essential/critical systems and displays in the cockpit.

Airworthiness Directives; Boeing Model 767 Airplanes · published 28 Nov 2007
The FAA is superseding an existing airworthiness directive (AD) that applies to all Boeing Model 767 airplanes. That AD currently requires repetitive measurements of the rudder and elevator freeplay, repetitive lubrications of rudder and elevator components, and related investigative/corrective actions if necessary. This new AD instead requires revised repetitive measurements of the rudder freeplay and the elevator freeplay for each of the power control actuators (PCAs) that move the rudder and elevator, corrective and related investigative actions if necessary, and repetitive lubrications of the rudder and elevator components. For some airplanes, this AD also requires related concurrent actions. This AD results from reports of freeplay-induced vibration of the rudder and the elevator. The potential for vibration of the control surface should be avoided because the point of transition from vibration to divergent flutter is unknown. We are issuing this AD to prevent excessive vibration of the airframe during flight, which could result in loss of control of the airplane.

The FAA is superseding an existing airworthiness directive (AD), which applies to certain transport category airplanes identified above. That AD currently requires modification of the reinforced flight deck door and other actions related to the reinforced flight deck door. Those other actions include modifying the door, inspecting and modifying wiring in the area, and revising the maintenance program to require more frequent testing of the decompression panels of the flight deck door. This new AD continues to require the existing requirements. This new AD adds airplanes to the existing requirement of a one-time inspection for chafing of wire bundles in the area of the flight deck door and corrective actions if necessary. This proposed AD also removes certain airplanes from the applicability. This AD results from a report of smoke and fumes in the cockpit of a Model 737-300 series airplane. We are issuing this AD to prevent inadvertent release of the decompression latch and consequent opening of the decompression panel in the flight deck door, or penetration of the flight deck door by smoke, any of which could result in injury to the airplane flightcrew. We are also proposing this AD to detect and correct wire chafing, which could result in arcing, fire, and/or reduced controllability of the airplane.

Airworthiness Directives; Pratt and Whitney PW4000 Series Turbofan Engines · published 25 Oct 2002
This amendment supersedes an existing airworthiness directive (AD) that is applicable to Pratt and Whitney (PW) model 4000 series turbofan engines. That action required PW4000 engines with potentially reduced stability margin to be limited to no more than one engine on each airplane, and required removing engines that exceed high pressure compressor (HPC) cycles-since-overhaul (CSO) or cycles-since-new (CSN) from service based on the engine's configuration and category. That action also required establishing a minimum build standard for engines that are returned to service, and performing cool-engine fuel spike testing (Testing-21) on engines to be returned to service after having exceeded HPC cyclic limits or after shop maintenance. This amendment establishes requirements similar to those in the existing AD being superseded, and introduces a rules-based criterion to determine the engine category classification for engines installed on Airbus A300 airplanes. This amendment also adds requirements to manage the engine configurations installed on Boeing 747 airplanes, and requires that repetitive Testing-21 be performed on certain configuration engines. This amendment also establishes criteria that requires Testing-21 on certain engines with Phase 0 or Phase 1, FB2T, or FB2B fan blade configurations. In addition, this amendment re- establishes high pressure compressor (HPC)-to-high pressure-turbine (HPT) cycles-since-overhaul (CSO) cyclic mismatch criteria, and adds criteria to address engine installation changes, engine transfers, and thrust rating changes. Also, this amendment establishes criteria to allow engine stagger without performing Testing-21 for engines which are over their respective limits. This amendment also introduces new requirements on the Phase 3, first run subpopulation engines which were identified after the issuance of NPRM Docket No. 2000-NE-47-AD. The Phase 3, first run subpopulation engines have a significant increase in surge rate and Testing-21 failure rate than the rest of the PW4000 fleet. In order to manage the subpopulation engines to preclude a dual-engine surge, immediate action is required. This immediately adopted rule includes the requirements proposed in the NPRM as well as the required actions for the Phase 3, first run subpopulation engines. This amendment is prompted by investigation and evaluation of PW4000 series turbofan engines surge data, and continuing reports of surges in the PW4000 fleet. The actions specified in this AD are intended to prevent engine takeoff power losses due to HPC surge. DATES: Effective November 12, 2002. The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register as of November 12, 2002. The incorporation by reference of certain other publications, as listed in the regulations, was approved previously by the Director of the Federal Register as of January 17, 2002 (67 FR 1, January2, 2002). Comments for inclusion in the Rules Docket must be received on or before December 24, 2002.

This new AD requires a test of the power distribution control units (PDCU) cards and generator control units (GCU) cards to detect faulty components, and if any faulty components are found, replacing any affected PDCU or GCU card. This AD was prompted by a determination that additional actions are necessary to address the identified unsafe condition. We are issuing this AD to detect and correct a leakage failure mode of transient voltage suppression (TVS) diodes used on PDCU cards or GCU cards in the primary power distribution boxes (PPDB), which, in combination with other system failures, could lead to loss of controllability of the airplane.

Airworthiness Directives; Fokker Services B.V. Airplanes · published 19 Apr 2012
We are adopting a new airworthiness directive (AD) for certain Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This AD was prompted by a report that the fuel crossfeed valves cannot be controlled when only emergency electrical power is available, that an unwanted configuration of the indication logic for the fuel fire shutoff valve was introduced during production, and that current fuel crossfeed indications are based on selection by the flightcrew instead of actual position of the crossfeed valve actuators. This AD requires modifying the crossfeed valve control and power supply, the crossfeed indication logic and power supply, and the indication logic for the fuel fire shutoff valve; modifying the overhead panel; and for certain airplanes, modifying the transfer logic of the center wing fuel tank. We are issuing this AD to prevent failure of an in-flight engine re- light following a double engine flame-out event, which could result in loss of the airplane.

Airworthiness Directives; Turbomeca S.A. Turboshaft Engines · published 14 Feb 2012
We are superseding an existing airworthiness directive (AD) for all Turbomeca S.A. Arriel 2B and 2B1 turboshaft engines. That AD currently requires checking the transmissible torque between the low- pressure (LP) pump impeller and the high-pressure (HP) pump shaft on high-pressure/low-pressure (HP/LP) pump hydro-mechanical metering units (HMUs) that do not incorporate Modification TU 147. This new AD requires inspection and possible replacement of the HMU. This AD was prompted by three additional cases of uncoupling of the HP/LP pump HMU LP fuel pump impeller and the HP fuel pump shaft, since the existing AD was issued. We are issuing this AD to prevent an uncommanded in-flight shutdown, which can result in a forced autorotation landing or accident.

Airworthiness Directives; Cessna Aircraft Company Models 172R, 172S, 182T, T182T, 206H, and T206H Airplanes · published 12 Apr 2007
The FAA is adopting a new airworthiness directive (AD) to supersede AD 2006-17-04, which applies to certain Cessna Aircraft Company (Cessna) Models 172R, 172S, 182T, T182T, 206H, and T206H airplanes. AD 2006-17-04 currently requires you to inspect the two end fittings on each of the flexible fuel hoses located in the engine compartment for the correct torque values, and, if any incorrect torque values are found during the inspection, tighten the hose end fittings to the correct torque values. This AD results from four reports of loose fuel lines connected to the fuel servo or fuel flow transducer. Two reports were of in-flight engine failure on a Model T182T airplane. A third report was of in-flight engine failure on a Model 206H airplane. A fourth report was of a Model 172S airplane losing engine power on final approach. Consequently, this AD would require you to establish the correct torque values of the end fittings on fuel hoses for certain Cessna Models 172R, 172S, 182T, T182T, 206H, and T206H airplanes. This AD clarifies that the torque values need to be physically established and visual inspection only is not sufficient. We are issuing this AD to detect and correct potential loss of fuel flow, which may result in partial or complete loss of engine power and/or uncontrolled engine compartment fire due to fuel leakage forward of the firewall.

The FAA is adopting a new airworthiness directive (AD) for certain Honeywell COM units and transponders, installed on but not limited to certain transport category airplanes. This AD requires a revision to the Normal Procedures section of the airplane flight manual to advise the flightcrew to check the status of the transponder after changing the air traffic control (ATC) code. This AD also requires replacing certain identification plate(s) with new plate(s), testing certain COM units or transponders as applicable, and corrective action if necessary. For certain airplanes, this AD requires replacing the transponders of certain COM units with new or modified transponders. For certain other airplanes, this AD requires installing a modification into certain transponders. This AD results from the transponder erroneously going into standby mode if the flightcrew takes longer than five seconds when using the rotary knob of the radio management unit to change the ATC code. We are issuing this AD to prevent the transponder of the COM unit from going into standby mode, which could increase the workload on the flightcrew and result in improper functioning of the traffic alert and collision avoidance system.

Airworthiness Directives; Saab Model SF340A and SAAB 340B Series Airplanes · published 9 Sep 1994
This document corrects a typographical error that appeared in the above-captioned airworthiness directive (AD), applicable to certain Saab Model SF340A and SAAB 340B series airplanes. That AD currently requires inspections to detect discrepancies of certain main landing gear (MLG) retract actuator bracket retaining bolts; replacement of discrepant parts; installation of washers, if necessary; and eventual replacement of certain MLG retract actuator bracket retaining bolts and certain nose landing gear (NLG) trunnion pin cross bolts. This action corrects terms in the compliance time specified for the requirement to remove the NLG trunnion pin cross bolts. This action is necessary to ensure that operators are not required to perform actions at a time that does not correspond with scheduled maintenance. DATES: Effective October 11, 1994. The incorporation by reference of certain publications listed in the regulations was previously approved by the Director of the Federal Register as of October 11, 1994 (59 FR 46543, September 9, 1994). ADDRESSES: The service information referenced in this AD may be obtained from Saab Aircraft AB, Product Support, S581.88, Link ping, Sweden. This information may be examined at the Federal Aviation Administration (FAA), Transport Airplane Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC. FOR FURTHER INFORMATION CONTACT: Mark Quam, Aerospace Engineer, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (206) 227-2145; fax (206) 227-1320. SUPPLEMENTARY INFORMATION: On August 24, 1994, the FAA issued AD 94-18-05, amendment 39-9018 (59 FR 46543, September 9, 1994), to require inspections to detect discrepancies of certain main landing gear (MLG) retract actuator bracket retaining bolts; replacement of discrepant parts; installation of washers, if necessary; and eventual replacement of certain MLG retract actuator bracket retaining bolts and certain nose landing gear (NLG) trunnion pin cross bolts. That action was prompted by reports of extension and retraction problems on the MLG, due to loose retract actuator brackets on the MLG shock struts. The actions required by that AD are intended to prevent a loose retract actuator bracket from interfering with the MLG shock strut trunnion support, which could result in the inability of the MLG to extend or retract. Recently, the FAAhas become aware of a typographical error that appeared in paragraph (c) of the published final rule, which would incorrectly require operators to replace the NLG trunnion pin cross bolts at a time that may not correspond with scheduled maintenance for the NLG. The compliance time for paragraph (c) was incorrectly published as, "At the next MLG overhaul, or within 12,000 landings after the effective date of the AD, whichever occurs earlier. . ." However, the correct compliance time for that requirement should have referred to ". . .at the next NLG overhaul." Since it is essential that operators perform the replacement in a timely manner and at a time when the NLG is normally serviced, this document corrects the compliance terms of paragraph (c) of AD 94-18-05, amendment 39-9018, to read as follows: "(c) At the next NLG overhaul, or within 12,000 landings after the effective date of this AD, whichever occurs earlier, remove the existing nose landing gear trunnion pin cross bolt, P/N NAS 1305-54D, and replace it with a new bolt, P/N NAS 1305-50D, in accordance with Paragraphs C. through F. of the Accomplishment Instructions of Saab Service Bulletin 340-32-094, dated October 29, 1993, or Revision 1, dated March 4, 1994." The effective date of the rule remains October 11, 1994. Since no other portion of the regulatory information has been changed, the final rule is not being republished. 94-18-05 SAAB AIRCRAFT AB: Amendment 39-9018. Docket 93-NM-234-AD. Applicability: Saab Model SF340A series airplanes, serial numbers 004 through 159, inclusive; and SAAB 340B series airplanes, serial numbers 160 through 346, inclusive; certificated in any category. Compliance: Required as indicated, unless accomplished previously. To prevent the inability of the main landing gear (MLG) to extend or retract, accomplish the following: (a) Within 600 landings after the effective date of this AD, or within 120 days after the effective date of this AD, whichever occurs earlier, accomplish the requirements of paragraphs (a)(1) and (a)(2) in accordance with Paragraphs 2.A. and 2.B. of the Accomplishment Instructions of Saab Service Bulletin 340-32-094, dated October 29, 1993, or Revision 1, dated March 4, 1994. (1) Perform a visual inspection of each MLG retract actuator bracket retaining bolt, Item 792A or 792 [part number (P/N) AIR 124792], as applicable, to detect corrosion, cracking, or damage, in accordance with the service bulletin. If any corrosion, cracking, or damage is detected during that inspection, prior to further flight, replace the existing bolt with a new or serviceable bolt in accordance with the service bulletin. (2) Perform a visual inspection of each MLG retract actuator bracket retaining bolt, Item 840 (P/N AIR 123940), to determine if the nut of the bolt is bottoming the threads in accordance with the service bulletin. If any nut bottoms the threads, prior to further flight, install washers in accordance with the service bulletin. (b) At the next MLG overhaul, or within 12,000 landings after the effective date of this AD, whichever occurs earlier, accomplish the requirements of paragraphs (b)(1) and (b)(2) of this AD in accordance with Paragraphs C. through F. of the Accomplishment Instructions of Saab Service Bulletin 340-32-094, dated October 29, 1993, or Revision 1, dated March 4, 1994. (1) Perform a visual and magnaflux inspection of each MLG retract actuator bracket retainer bolt, Item 792A or 792 (P/N AIR 124792), as applicable, to detect any scored, cracked, or out-of-tolerance condition, in accordance with the service bulletin. If any bolt is found to be scored, cracked, or out-of-tolerance, prior to further flight, replace the bolt with a serviceable magnafluxed bolt or with a new bolt, in accordance with the service bulletin. NOTE 1: In accordance with normal maintenance practices, the retainer bolts also should be visually inspected for corrosion when they are removed during the accomplishment of the inspections required by this paragraph. Any corroded bolt that is detected should be replaced with a serviceable bolt or a new bolt. Instructions for performing visual inspections of the retainer bolts to detect corrosion are contained in Attachments 1, 2, 5, 6, and 7 of Saab Service Bulletin 340-32-094. (2) Replace each existing MLG retract actuator bracket retaining bolt, Item 840 (P/N AIR 123940), with a new bolt, P/N AIR 134736, in accordance with the service bulletin. (c) At the next NLG overhaul, or within 12,000 landings after the effective date of this AD, whichever occurs earlier, remove the existing nose landing gear trunnion pin cross bolt, P/N NAS 1305-54D, and replace it with a new bolt, P/N NAS 1305-50D, in accordance with Paragraphs C. through F. of the Accomplishment Instructions of Saab Service Bulletin 340-32-094, dated October 29, 1993, or Revision 1, dated March 4, 1994. (d) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Standardization Branch, ANM-113. NOTE 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Manager, Standardization Branch, ANM-113. (e) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished. (f) The actions shall be done in accordance with the following Saab service bulletins, which contain the following list of effective pages: Saab Service Bulletin and Date Page NumberRevision Level Shown on Page Date Shown on Page 340-32-094, October 29, 1993 Title page 1-5 Original (These pages are not dated.)
