Is AD 2003-02-01 a recurring Airworthiness Directive?

No — AD 2003-02-01 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2003-02-01 apply to?

AD 2003-02-01 applies to Honeywell — models ALF502, LF507. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Honeywell International, Inc., (formerly AlliedSignal, Inc. and Textron Lycoming) ALF502L-2, ALF502L-2C, ALF502R-3 and ALF502R-3A Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Honeywell International, Inc., (formerly AlliedSignal, Inc. and Textron Lycoming) ALF502L-2, ALF502L-2C, ALF502R-3 and ALF502R-3A series turbofan engines. This action requires inspection of the flow divider primary, secondary, and drain tube assemblies for security and proper clamping. This amendment is prompted by a fire in the engine nacelle of an ALF502L-2C powered airplane caused by fracture of the flow divider left primary fuel tube, due to high-cycle fatigue resulting from a missing support clamp. The actions specified in this AD are intended to prevent fire in the engine nacelle, in-flight shutdown, and possible damage to the engine.

ModelsALF502, LF507

Applies regardless of prior modification, alteration, or repair. One-time inspection of flow divider primary, secondary, and drain tube clamp installation required within 100 flight hours, per Honeywell (formerly AlliedSignal/Textron Lycoming) Alert Service Bulletin ALF/LF A73-1013, dated October 18, 2002, to prevent nacelle fire and in-flight shutdown.

Whether AD 2003-02-01 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 2003-02-01 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.
