E7-22810 Airworthiness Directives; Rolls-Royce Corporation AE 3007A and AE 3007C Series Turbofan Engines Rule The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce Corporation (RRC) AE 3007A and AE 3007C series turbofan engines.

This AD also requires those actions and would also require a terminating action. This AD results from design improvements to components in the accessory gearbox air turbine starter mounting pad. We are issuing this AD to prevent an in-flight engine shutdown due to loss of engine oil from the engine accessory gearbox starter pad shaft seal drain and possible loss of the airplane. 2007-11-28 2007 11 https://www.federalregister.gov/documents/2007/11/28/E7-22810/airworthiness-directives-rolls-royce-corporation-ae-3007a-and-ae-3007c-series-turbofan-engines https://www.govinfo.gov/content/pkg/FR-2007-11-28/pdf/E7-22810.pdf Transportation Department; Federal Aviation Administration 492,159 The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce Corporation (RRC) AE 3007A and AE 3007C series turbofan engines.
