Is AD 2002-12-15 a recurring Airworthiness Directive?

Yes — AD 2002-12-15 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2002-12-15 apply to?

AD 2002-12-15 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 supersedes an existing airworthiness directive (AD), that is applicable to Pratt & Whitney PW4000 series turbofan engines. That AD requires operators to perform initial and repetitive inspections for cracking of high pressure compressor (HPC) front drum rotors based on cycle usage. That AD also requires the removal from service of any cracked HPC front drum rotors. This amendment clarifies inspection requirements for cracking of HPC front drum rotors that have fewer than 1,000 cycles-since-new (CSN). This amendment is prompted by comments from operators seeking more clarity about the inspection requirements of paragraph (a)(1) of that AD. The actions specified by this AD are intended to prevent HPC drum rotor failure from cracks that could result in an uncontained engine failure and damage to the airplane.

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.

MakesPratt & Whitney

ModelsPW4000

Applies to the high pressure compressor (HPC) front drum rotor; borescope/eddy-current inspection interval keyed to cycles-since-new (CSN) at the effective date, per PW ASB PW4ENG A72-722 (dated Sept 29, 2000, or Rev 1 dated June 7, 2001).

Whether AD 2002-12-15 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.
