Is AD E9-29987 a recurring Airworthiness Directive?

Yes — AD E9-29987 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Airworthiness Directive E9-29987

Q: Which aircraft does AD E9-29987 apply to?

AD E9-29987 applies to Honeywell International — models ALF502L series, ALF502R series, LF507-1F, LF507-1H, ALF502, LF507. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Honeywell International Inc. ALF502 Series and LF507 Series Turbofan Engines

What this AD requires

The FAA is superseding an existing airworthiness directive (AD) for Honeywell International Inc. ALF502 series and LF507 series turbofan engines with certain fuel manifold assemblies installed. That AD currently requires initial and repetitive on-wing eddy current or in-shop fluorescent penetrant inspections of certain part number (P/N) fuel manifold assemblies for cracks, and replacement of cracked fuel manifolds with serviceable manifolds. This AD continues to require inspecting those fuel manifolds for cracks, adds leak checks of certain additional P/N fuel manifolds, and specifies replacement of the affected manifolds as an optional terminating action in lieu of the repetitive inspections. This AD results from reports of fire in the engine nacelle. We are issuing this AD to detect cracks in certain fuel manifolds and fuel leaks from other fuel manifolds, which could result in a fire in the engine nacelle and a hazard to the aircraft.

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

Applies only when a fuel manifold with one of the listed part numbers is installed.

Whether AD E9-29987 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.

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.
