Airworthiness Directives; Pratt & Whitney Division Turbofan Engines

What this AD requires

We are adopting a new airworthiness directive (AD) for certain Pratt & Whitney (PW) PW4164, PW4164-1D, PW4168, PW4168-1D, PW4168A, PW4168A-1D, and PW4170 turbofan engines. This AD was prompted by several instances of fuel leaks on PW engines installed with the Talon IIB combustion chamber configuration. This AD requires initial and repetitive inspections of the affected fuel nozzles and their replacement with parts eligible for installation. We are issuing this AD to prevent failure of the fuel nozzles, which could lead to engine fire and damage to the airplane.

Repetitive inspection. Re-inspect every 800 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Applies to: (1) PW4164, PW4168, and PW4168A engines that incorporated SB PW4G-100-72-214 (dated Dec 15, 2011) or SB PW4G-100-72-219 Rev 1 (or original issue, dated Oct 5, 2011), with fuel nozzles P/N 51J345 installed; (2) PW4168A engines with Talon IIA outer combustion chamber assembly P/N 51J100 and fuel nozzles P/N 51J345 with S/N CGGUA19703 through CGGUA19718 inclusive or CGGUA22996 and higher installed; (3) PW4168A-1D and PW4170 engines with engine S/N P735001 through P735190 inclusive and fuel nozzles P/N 51J345 installed; and (4) PW4164-1D, PW4168-1D, PW4168A-1D, and PW4170 engines that incorporated SB PW4G-100-72-220 Rev 4 or earlier (dated Sept 30, 2011), with fuel nozzles P/N 51J345 installed.

Whether AD 2016-22-05 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 2016-22-05 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.
