Is AD 96-13-08 a recurring Airworthiness Directive?

Yes — AD 96-13-08 requires a repetitive inspection every 450 hours. Next-due depends on the aircraft's time in service.

Which aircraft does AD 96-13-08 apply to?

AD 96-13-08 applies to Pratt & Whitney — models PW4000. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Pratt & Whitney PW4000 Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Pratt & Whitney (PW) PW4000 series turbofan engines. This action requires initial and repetitive inspections of the aft cascade support frame assembly of thrust reverser for cracks, and replacement, if necessary, with serviceable parts; or lockout of the thrust reversers. This amendment is prompted by reports of aft cascade support frame assembly failures. The actions specified in this AD are intended to prevent aft cascade support frame assembly failure due to cracks, which can result in thrust reverser hardware liberation and ejection from the aircraft during thrust reverser operation, which can contaminate the runway with debris, causing an operational hazard to other aircraft during takeoff and landing.

Repetitive inspection. Re-inspect every 450 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Part-conditional — 221-0516-503, 221-0516-504.

Applies only to PW4000 series engines equipped with thrust reversers under STC No. SJ514NE (Airbus A300-600/A310) or STC No. SE744NE (McDonnell Douglas MD-11), where those thrust reversers incorporate aft cascade support frame assemblies P/N 221-0516-503 or P/N 221-0516-504.

Whether AD 96-13-08 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 96-13-08 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.
