Boeing 787s Grounded Over Dual Engine Shutdown Risk
The Federal Aviation Administration (FAA) has proposed mandatory fan cowl modifications on certain Boeing 787 Dreamliners due to concerns over a potential dual engine shutdown in flight.
The issue centers on the left fan cowl of the aircraft's right engine, where debris from an uncontained rotor failure in the left engine could damage critical components and potentially cause both engines to shut down.
Boeing reported the problem to the FAA and developed changes to address it. The manufacturer issued a Special Attention Requirements Bulletin on February 19, 2026, outlining inspections and modifications for affected aircraft.
The proposed airworthiness directive (AD) applies to Boeing 787-8, 787-9, and 787-10 aircraft powered by Rolls-Royce Trent 1000 engines. The FAA estimates that 22 aircraft on the US registry would be affected.
