Abstract
We are adopting a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW4164-1D, PW4168-1D, PW4168A-1D and PW4170 engines, and certain PW4164, PW4168, and PW4168A turbofan engines. This AD was prompted by fuel nozzle-to-fuel supply manifold interface fuel leaks. This AD requires inspecting fuel nozzles for signs of leakage, replacing hardware as required, and torqueing to specified requirement. We are issuing this AD to prevent fuel leaks which could result in engine fire and damage to the airplane.
