| 2017-04627 | Airworthiness Directives; Pratt & Whitney Division Turbofan Engines | Rule | We are adopting a new airworthiness directive (AD) for all Pratt & Whitney Division (PW) PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090-3 turbofan engines. This AD was prompted by an uncontained failure of a high-pressure turbine (HPT) hub during takeoff. This AD requires an inspection to measure the surface condition of the aft side web/rim fillet of HPT 1st stage hubs and removal from service of hubs that fail inspection. We are issuing this AD to correct the unsafe condition on these products. | 2017-03-09 | 2017 | 3 | https://www.federalregister.gov/documents/2017/03/09/2017-04627/airworthiness-directives-pratt-and-whitney-division-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2017-03-09/pdf/2017-04627.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We are adopting a new airworthiness directive (AD) for all Pratt & Whitney Division (PW) PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090-3 turbofan engines.
