We propose to supersede Airworthiness Directive (AD) 2016-22- 05, which applies to certain Pratt & Whitney Division (PW) PW4164, PW4164-1D, PW4168, PW4168-1D, PW4168A, PW4168A-1D, and PW4170 turbofan engines. AD 2016-22-05 requires initial and repetitive inspections of the affected fuel nozzles and their replacement with parts eligible for installation. Since we issued AD 2016-22-05, PW introduced newly forged fuel nozzles, fuel manifold brackets, and clamps. This proposed AD would require 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 supply manifold assemblies with parts eligible for installation. We are proposing this AD to address the unsafe condition on these products.
