Is AD 2001-15-02 a recurring Airworthiness Directive?

Yes — AD 2001-15-02 requires a repetitive inspection every 18 months. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2001-15-02 apply to?

AD 2001-15-02 applies to Boeing — models 747. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Boeing Model 747 Series Airplanes Powered By Pratt & Whitney JT9D-3 and -7 Series Engines

What this AD requires

This amendment supersedes an existing airworthiness directive (AD), applicable to certain Boeing Model 747 series airplanes, that currently requires repetitive inspections and torque checks of the hanger fittings and strut forward bulkhead of the forward engine mount and adjacent support structure, and corrective actions, if necessary. The existing AD also provides for optional terminating action for the repetitive inspections and checks. This amendment requires certain new repetitive torque checks and the previously optional terminating action. The actions specified by this AD are intended to prevent loose fasteners and associated damage to the hanger fittings and bulkhead of the forward engine mount, which could result in separation of the engine from the airplane.

Repetitive inspection. Re-inspect every 18 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Restatement of AD 2000-23-16 requirements; inspection/torque-check of forward engine mount hanger fittings and strut forward bulkhead per Boeing Alert SB 747-54A2203, dated Aug 31, 2000. Specific serial/model applicability list is in the AD's preceding provision, not captured in this excerpt.

Whether AD 2001-15-02 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 compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 2001-15-02 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.
