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 certain Pratt & Whitney (PW) JT8D-200 series turbofan engines. This amendment requires the installation of stops on the fan exit guide vane case. This amendment is prompted by reports of the flange between the fan duct case and the fan exit guide vane case separating due to a fan blade fracture event. The actions specified by this AD are intended to prevent the flange between the fan duct case and the fan exit guide vane case from separating due to a fan blade failure. Separations of that flange could result in damage to the airplane.

Which aircraft AD 2002-21-17 applies to

MakesPratt & Whitney

Part-conditional — 315T1604-2, 315T1604-5, 315T1604-6.

AD requires installing stops on the fan exit guide vane case at next shop visit, per Pratt & Whitney SB No. 6100, Revision 2 (1998-12-09), to prevent flange separation between fan duct and fan exit guide vane from fan blade failure. Engines with stops already installed per SB 6100 Rev 1 (1992-04-09) or original issue (1992-11-09) are in compliance. Specific engine model not stated in retrieved text.

Whether AD 2002-21-17 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 2002-21-17 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.
