Abstract

The FAA proposes to adopt 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 proposed 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 proposed AD would require replacing Pb sensors. The FAA is proposing this AD to address the unsafe condition on these products.
