Airworthiness Directives; Pratt & Whitney Canada Corp. Turboprop Engines

What this AD requires

We are superseding airworthiness directive (AD) 2014-14-02 for certain Pratt & Whitney Canada Corp. (P&WC) PW120, PW121, PW121A, PW124B, PW127, PW127E, PW127F, PW127G, and PW127M turboprop engines. AD 2014-14-02 required removal of the O-ring seal from the fuel manifold fitting. This new AD requires replacement of the fuel nozzle and the fuel manifold flow adapter. This AD was prompted by reports of fuel leaks at the interface between the fuel manifold and the fuel nozzle that resulted in engine fire. We are issuing this AD to correct the unsafe condition on these products.

Which aircraft AD 2015-20-03 applies to

MakesPratt & Whitney Canada
Models120, 121, 121A, 124B, 127, 127E, 127F, 127G, 127M, PW100
Serial-conditional — narrows to serials ?–PCE-EB0366, ?–PCE-AX0275, ?–PCE-ED0810.

PW120, PW121, and PW121A apply only in post-SB-21610 configuration. PW124B, PW127, PW127E, and PW127F apply only in post-SB-21607 configuration. PW127E and PW127F also apply with S/Ns PCE-EB0366 and earlier. PW127G applies with S/Ns PCE-AX0275 and earlier. PW127M applies with S/Ns PCE-ED0810 and earlier.

Whether AD 2015-20-03 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 2015-20-03 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.
