| 2013-19429 | Airworthiness Directives; Pratt & Whitney Division Turbofan Engines | Rule | We are adopting a new airworthiness directive (AD) for all Pratt & Whitney Division (PW) turbofan engine model PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090-3 with a certain second- stage high-pressure turbine (HPT) air seal part number installed. This AD was prompted by discovery of cracks in second-stage HPT air seals. This AD requires inspection and removal from service of HPT air seals that fail inspection. We are issuing this AD to prevent failure of the second-stage HPT air seal, which could lead to an uncontained engine failure and damage to the airplane. | 2013-08-13 | 2013 | 8 | https://www.federalregister.gov/documents/2013/08/13/2013-19429/airworthiness-directives-pratt-and-whitney-division-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2013-08-13/pdf/2013-19429.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We are adopting a new airworthiness directive (AD) for all Pratt & Whitney Division (PW) turbofan engine model PW4074, PW4074D, PW4077, PW4077D, PW4084D, PW4090, and PW4090-3 with a certain second- stage high-pressure turbine (HPT) air seal part number... |
