| 2018-12830 | Airworthiness Directives; Pratt & Whitney Division Turbofan Engines | Rule | We are adopting 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 AD was prompted by the discovery of multiple cracked 4th stage low-pressure turbine (LPT) air seals in the fleet. This AD requires removal from service of certain 4th stage LPT air seals. We are issuing this AD to address the unsafe condition on these products. | 2018-06-15 | 2018 | 6 | https://www.federalregister.gov/documents/2018/06/15/2018-12830/airworthiness-directives-pratt-and-whitney-division-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2018-06-15/pdf/2018-12830.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We are adopting 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,... |
