Airworthiness Directives; Pratt & Whitney Canada PW100 Series Turboprop Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD), applicable to Pratt & Whitney Canada (PWC) PW100 series turboprop engines, that requires removal of the existing fuel manifold tubes, lock plates, and preformed packing; installation of improved fuel manifold transfer tubes, improved lock plates, and improved preformed packing; and, after installation, the performance of a leak check. This amendment is prompted by reports of engine fuel leaks which resulted in either inflight engine shutdowns or fire warnings. The actions specified by this AD are intended to prevent engine fuel leaks, which can result in inflight engine shutdowns or fire warnings.

Applies to each identified engine regardless of modification, alteration, or repair; if the requirements of the AD are affected by a modification/alteration/repair, owner/operator must request approval for an alternative method of compliance.

Whether AD 98-14-02 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 98-14-02 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.
