Press the magnifying glass in the top bar and type in “Search anything”. One search looks through your own aircraft records, the airworthiness directives and manufacturer service documents, the technical data, the regulations, the FAA aircraft registrations, and Help. The results are grouped under those headings, and a group with nothing in it says so.
A registration, a name, a model number, a document reference, or a whole question all work. Every word you type must appear, in any order: “ELT battery” finds an entry reading “Replaced ELT batteries”. Singular and plural find each other.
The public Directive Search takes a part number, a manufacturer, what the part is, or a directive’s own number. Typing 2026-17-10, with or without “AD”, puts that directive first.
