| 2020-27985 | Airworthiness Directives; CFM International, S.A. Turbofan Engines | Rule | The FAA is adopting a new airworthiness directive (AD) for certain CFM International, S.A. (CFM) LEAP-1A23, LEAP-1A24, LEAP- 1A24E1, LEAP-1A26, LEAP-1A26CJ, LEAP-1A26E1, LEAP-1A29, LEAP-1A29CJ, LEAP-1A30, LEAP-1A32, LEAP-1A33, LEAP-1A33B2, LEAP-1A35A model turbofan engines. This AD was prompted by an investigation by CFM that showed a subsurface anomaly in a part manufactured using the same material as the LEAP-1A high-pressure turbine (HPT) stage 2 disk. This AD requires an ultrasonic inspection (UI) of the HPT stage 2 disk and replacement of any HPT stage 2 disk that fails the UI with a part eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products. | 2020-12-21 | 2020 | 12 | https://www.federalregister.gov/documents/2020/12/21/2020-27985/airworthiness-directives-cfm-international-sa-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2020-12-21/pdf/2020-27985.pdf | Transportation Department; Federal Aviation Administration | 492,159 | The FAA is adopting a new airworthiness directive (AD) for certain CFM International, S.A.
