Is AD 2003-13-11 a recurring Airworthiness Directive?

Yes — AD 2003-13-11 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Airworthiness Directive 2003-13-11

Q: Which aircraft does AD 2003-13-11 apply to?

AD 2003-13-11 applies to Pratt & Whitney Division — models PW4074, PW4074D, PW4077, PW4077D, PW4090, PW4090-3, PW4000. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Pratt & Whitney PW4074, PW4074D, PW4077, PW4077D, PW4090, and PW4090-3 Turbofan Engines

What this AD requires

The FAA is adopting a new airworthiness directive (AD) for Pratt & Whitney (PW) PW4074, PW4074D, PW4077, PW4077D, PW4090, and PW4090-3 turbofan engines with high pressure compressor (HPC) rear cases, part numbers (P/Ns) 55H425-01, 55H385-01, and 56H396-01 installed. This AD requires initial and repetitive visual or fluorescent penetrant inspections (FPI) of the J flange on the HPC rear case, and removal from service of the rear case based on certain inspection results. This AD is prompted by reports of cracks propagating from bolt holes in the HPC rear case J flange, and reports of high-cycle HPC rear cases exhibiting cracks propagating into the shell wall. The actions specified in this AD are intended to prevent fracturing and rupturing of the HPC rear case, resulting in uncontained engine failure.

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.

ModelsPW4074, PW4074D, PW4077, PW4077D, PW4090, PW4090-3, PW4000

Part-conditional — 55H425-01, 55H385-01, 56H396-01.

Applies only to engines with HPC rear case P/N 55H425-01, 55H385-01, or 56H396-01 installed (scalloped J-flange configuration produced or modified per PW service bulletin PW4G-112-72-150, -151, or -195); adds an inspection at bolt hole location 69 not in the original PW service bulletin PW4G-112-72-256.

Whether AD 2003-13-11 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.
