2014-28189 Airworthiness Directives; Rolls-Royce plc Turbofan Engines Rule We are superseding airworthiness directive (AD) 98-07-07 for all Rolls-Royce plc (RR) RB211-535E4 and RB211-535E4-B turbofan engines. AD 98-07-07 required removing certain part number (P/N) low- pressure (LP) fuel filter-to-high-pressure (HP) fuel pump tube assemblies and installing flexible LP fuel filter-to-HP fuel pump tube assemblies. This AD expands the applicability of AD 98-07-07 to include the RB211-535E4-C-37 turbofan engine and requires removal from service of additional P/N LP fuel filter-to-high-pressure HP fuel pump tube assemblies. This AD was prompted by reports of fuel leaks that have resulted in a number of engine in-flight shutdowns. We are issuing this AD to prevent loss of fuel supply to the engine, which could lead to an in-flight shutdown of one or more engines, loss of thrust control, and damage to the airplane. 2014-12-02 2014 12 https://www.federalregister.gov/documents/2014/12/02/2014-28189/airworthiness-directives-rolls-royce-plc-turbofan-engines https://www.govinfo.gov/content/pkg/FR-2014-12-02/pdf/2014-28189.pdf Transportation Department; Federal Aviation Administration 492,159 We are superseding airworthiness directive (AD) 98-07-07 for all Rolls-Royce plc (RR) RB211-535E4 and RB211-535E4-B turbofan engines.
