| 2016-26334 | Airworthiness Directives; Rolls-Royce plc Turbofan Engines | Proposed Rule | We propose to supersede airworthiness directive (AD) 2014-16- 10 that applies to all Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines. AD 2014-16-10 requires initial and repetitive ultrasonic inspections (UIs) of the affected low-pressure (LP) compressor blades. Since we issued AD 2014-16-10, RR issued revised service information to reduce the inspection threshold. This proposed AD would retain the UIs in AD 2014-16-10 while applying the revised inspection threshold. We are proposing this AD to prevent LP compressor blade airfoil separations, damage to the engine, and damage to the airplane. | 2016-11-01 | 2016 | 11 | https://www.federalregister.gov/documents/2016/11/01/2016-26334/airworthiness-directives-rolls-royce-plc-turbofan-engines | https://www.govinfo.gov/content/pkg/FR-2016-11-01/pdf/2016-26334.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We propose to supersede airworthiness directive (AD) 2014-16- 10 that applies to all Rolls-Royce plc (RR) RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines.
