Is AD 2002-23-14 a recurring Airworthiness Directive?

Yes — AD 2002-23-14 requires a repetitive inspection. Next-due depends on the aircraft's time in service.

Which aircraft does AD 2002-23-14 apply to?

AD 2002-23-14 applies to Pratt & Whitney — models JT8D. Serial/part conditions may narrow it to specific aircraft.

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

What this AD requires

This amendment adopts a new airworthiness directive (AD), that is applicable to Pratt & Whitney (PW) JT8D-200 series turbofan engines. This amendment requires initial and repetitive visual inspections, fluorescent magnetic particle inspections (FMPI), and fretting wear inspections of high pressure compressor (HPC) front hubs that have operated with PWA-110 coating in the interface between the hub and the stage 8-9 spacer. This amendment is prompted by the discovery of cracked tierod holes found during routine engine overhauls. The actions specified by this AD are intended to prevent a rupture of the HPC front hub 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.

Which aircraft AD 2002-23-14 applies to

MakesPratt & Whitney

ModelsJT8D

Applies to HPC front hubs and stage 8-9 spacers on JT8D engines; inspection (strip coating, visual fretting check, FMPI, replate) and replacement-as-needed schedule based on total cycles-in-service (CIS) at the AD effective date, per P&W Alert SB JT8D A6430, dated September 5, 2002; optional terminating action is a Nickel-Cadmium or Electroless Nickel plated hub/spacer that never operated with PWA-110 coating at the interface.

Whether AD 2002-23-14 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 2002-23-14 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.
