FAA Adopts New Airworthiness Directive for Pratt & Whitney JT8D-9 Engines
Summary
The Federal Aviation Administration (FAA) has adopted a new airworthiness directive for Pratt & Whitney's JT8D-9, -9A, -11, -15, -17, and -17R turbofan engines, requiring overhauling of fan blade leading edges after 4,000 cycles-in-service to prevent high-cycle fatigue cracking and potential uncontained failures.
