Airworthiness Directives; Pratt & Whitney Division Turbofan Engines

What this AD requires

We are superseding Airworthiness Directive (AD) 2016-22-05 for certain Pratt & Whitney Division (PW) PW4164, PW4164-1D, PW4168, PW4168-1D, PW4168A, PW4168A-1D, and PW4170 model turbofan engines. AD 2016-22-05 required initial and repetitive inspections of the affected fuel nozzles and their replacement with parts eligible for installation. This AD requires initial and repetitive inspections of the affected fuel nozzles and fuel nozzle supply manifold assemblies, replacement of the affected fuel nozzles with parts eligible for installation, and the installation of new brackets and clamps on the fuel nozzle supply manifold assemblies. This AD was prompted by several instances of fuel leaks on PW engines with the Talon IIB combustion chamber configuration installed. We are issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect every 24 months. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Complex multi-part applicability: (1) PW4164/PW4168/PW4168A engines with fuel nozzle P/N 51J345 installed AND Talon IIB combustion chamber (SB PW4G-100-72-214) or RCC HPC (SB PW4G-100-72-219) or outer combustion chamber waspaloy nuts (SB PW4G-100-72-253) installed; (2) PW4168A engines with Talon IIA outer combustion chamber P/N 51J100 or 51J382 and fuel nozzle P/N 51J345 installed; (3) PW4168A-1D and PW4170 engines, S/N P735001 through P735190 inclusive, with fuel nozzle P/N 51J345 installed; (4) PW4164-1D/PW4168-1D/PW4168A-1D/PW4170 engines with RCC HPC per SB PW4G-100-72-220 Rev.4 or earlier and fuel nozzle P/N 51J345 installed; (5) PW4164/PW4164-1D/PW4168/PW4168-1D/PW4168A/PW4168A-1D/PW4170 engines with fuel nozzle P/N 51J398 installed and NOT having installed the replacement fuel nozzle supply manifold assemblies per SB PW4G-100-73-48 Rev.1.

Whether AD 2019-06-07 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 2019-06-07 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.
