What Happened
Regulator Acts Over Dual Engine Shutdown Risk
The Federal Aviation Administration (FAA) is proposing a mandatory modification to the fan cowl of certain Boeing 787 Dreamliners to mitigate the risk of dual engine shutdown in the event of an uncontained engine failure. The issue affects aircraft powered by Rolls-Royce Trent 1000 engines, with 22 US-registered aircraft potentially impacted. Boeing had previously issued a Special Attention Requirements Bulletin outlining inspections and modifications for affected aircraft. The FAA’s proposed airworthiness directive would make these instructions mandatory for US operators, with compliance times to follow Boeing’s requirements once a final rule takes effect. The proposal was reported by AeroTime.
