2017-21558 Airworthiness Directives; Pratt & Whitney Division Turbofan Engines Proposed Rule We propose to adopt a new airworthiness directive (AD) for all Pratt & Whitney Division (PW) PW4052, PW4056, PW4060, PW4062, PW4062A, PW4152, PW4156A, PW4158, PW4460, and PW4462 turbofan engine models, including engines identified with suffixes -1C, -1E, -3, -3A, or -3B. This proposed AD was prompted by the discovery of multiple cracked 4th stage low-pressure turbine (LPT) air seals in the fleet. This proposed AD requires removal from service of certain air seals. We are proposing this AD to correct the unsafe condition on these products. 2017-10-12 2017 10 https://www.federalregister.gov/documents/2017/10/12/2017-21558/airworthiness-directives-pratt-and-whitney-division-turbofan-engines https://www.govinfo.gov/content/pkg/FR-2017-10-12/pdf/2017-21558.pdf Transportation Department; Federal Aviation Administration 492,159 We propose to adopt a new airworthiness directive (AD) for all Pratt & Whitney Division (PW) PW4052, PW4056, PW4060, PW4062, PW4062A, PW4152, PW4156A, PW4158, PW4460, and PW4462 turbofan engine models, including engines identified with suffixes -1C,...
