Airworthiness Directives; Pratt & Whitney JT8D-200 Series Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that applies to Pratt & Whitney (PW) JT8D-209, -217, -217A, -217C, and -219 series turbofan engines. This amendment requires removal and replacement of protective coating of the 7th and 9th through 12th stage high pressure compressor (HPC) disks and the 8th stage HPC hub, initial and repetitive inspections for corrosion pits and cracks, and removal from service as required. This amendment is prompted by reports from operators of cracks observed in JT8D engine steel HPC disks. We are issuing this AD to prevent fracture of the 7th and 9th through 12th stage HPC disks and 8th stage HPC hub, resulting in 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.

Which aircraft AD 2003-16-05 applies to

MakesPratt & Whitney
ModelsJT8D

Specific JT8D model designations not stated in retrieved applicability text; addresses corrosion pits/cracks in 7th and 9th-through-12th stage HPC disks and 8th stage HPC hub, remedied per Pratt & Whitney alert service bulletin JT8D A6435, Revision 1, dated March 7, 2003.

Whether AD 2003-16-05 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 2003-16-05 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.
