Airworthiness Directive · Amendment 39-11050 · BMW Rolls-Royce GmbH Models BR700- 710A1-10 and BR700-710A2-20 Turbofan Engines
BMW Rolls-Royce GmbH Models BR700- 710A1-10 and BR700-710A2-20 Turbofan Engines
BMW Rolls-Royce GmbH (BRR) Model BR700-710A1-10 and BR700-710A2-20 turbofan engines installed on, but not limited to, Gulfstream Aerospace G-V and Bombardier BD-700-1A10 model aircraft.
This document publishes in the Federal Register an amendment adopting Airworthiness Directive (AD) 98-24-03 that was sent previously to all known U.S. owners and operators of BMW Rolls-Royce GmbH (BRR) Models BR700-710A1-10 and BR700-710A2-20 turbofan engines by individual letters. This AD requires repetitive visual inspections of the fairing and fasteners for correct installation and damage, and verification that the engine core fairing fasteners are torqued to the higher torque value. This amendment is prompted by a report of an engine compressor core fairing failure during engine ground runs. The actions specified by this AD are intended to prevent engine compressor or combustion core fairing detachment and damage to the engine bypass duct, resulting in engine failure and damage to the aircraft.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
