| 2020-28042 | Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (Type Certificate Previously Held by Rolls-Royce plc) Turbofan Engines | Proposed Rule | The FAA proposes to adopt a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000-A2, 1000-AE2, 1000-C2, 1000-CE2, 1000-D2, 1000-E2, 1000-G2, 1000-H2, 1000- J2, 1000-K2 and 1000-L2 model turbofan engines. This proposed AD was prompted by the manufacturer's analysis which determined that cracks may initiate in the front seal fins and cause cracks in the low- pressure turbine (LPT) disk. This proposed AD would require repetitive inspection of the seal fins and, depending on the results of the inspection, replacement of the LPT disk before further flight. The FAA is proposing this AD to address the unsafe condition on these products. | 2020-12-21 | 2020 | 12 | https://www.federalregister.gov/documents/2020/12/21/2020-28042/airworthiness-directives-rolls-royce-deutschland-ltd-and-co-kg-type-certificate-previously-held-by | https://www.govinfo.gov/content/pkg/FR-2020-12-21/pdf/2020-28042.pdf | Transportation Department; Federal Aviation Administration | 492,159 | The FAA proposes to adopt a new airworthiness directive (AD) for certain Rolls-Royce Deutschland Ltd & Co KG (RRD) Trent 1000-A2, 1000-AE2, 1000-C2, 1000-CE2, 1000-D2, 1000-E2, 1000-G2, 1000-H2, 1000- J2, 1000-K2 and 1000-L2 model turbofan engines.... |
