Builders Log

The record of the build, kept where the work happens

Open to every account while it is under test. After that it becomes part of the Hangar Flying membership, $99 a year. What a membership includes

An entry in a minute, from a phone

What you did, the photographs and the hours. Save and sign finishes it in one press; the rest is under More detail.

Parts with real fields

Manufacturer, model, part number and serial number, entered once. The same equipment list serves the panel, the build and the aircraft after it flies.

Service data from the first day

A part on the equipment list is checked against airworthiness directives and manufacturer service documents while the aircraft is still being built.

The record stays with the aircraft

The log is kept for the life of the aircraft and can be taken out whole on any day: every entry and every photograph.
