Airworthiness Directives; Pratt & Whitney Canada PW100 Series Turboprop Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Pratt & Whitney Canada PW100 series turboprop engines. This action requires a visual inspection of the two gas generator case drain ports to ensure that they are connected to drain lines or capped in accordance with the applicable aircraft installation configuration. This amendment is prompted by a report of a nacelle fire. The actions specified in this AD are intended to prevent a nacelle fire caused by fluid leaking from the gas generator case drain ports.

Whether AD 97-17-05 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 97-17-05 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.
