Airworthiness Directives; Boeing Model 747-100, -200, -300, -400, and 747SR Series Airplanes

What this AD requires

This amendment adopts a new airworthiness directive (AD); applicable to all Boeing Model 747-100, -200, -300, -400, and 747SR series airplanes; that requires a one-time inspection to determine whether H-11 steel bolts are installed as attach and support bolts at the trailing edge flap transmissions, and replacement of any H-11 steel bolt with an Inconel bolt. The actions specified by this AD are intended to prevent loss of a flap transmission, which could reduce lateral controllability of the airplane.

applicability derived from the AD summary — confirm the model/serial from the records

Whether AD 01-3699 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 01-3699 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
