Summary
The FAA is adopting a new airworthiness directive (AD) for all Pratt & Whitney Division (PW) Model PW4052, PW4056, PW4060, PW4060A, PW4060C, PW4062, PW4062A, PW4152, PW4156, PW4156A, PW4158, PW4460, and PW4462 engines. This AD was prompted by multiple reports of tailpipe fire, loss of thrust control, and engine in-flight shutdown due to undetected deterioration of pressure burner (Pb) sensors. This AD requires replacing Pb sensors. The FAA is issuing this AD to address the unsafe condition on these products.
