FAA Proposes Airworthiness Directive for Rolls-Royce RB211-Trent 500, 700, and 800 Engines

Summary

The Federal Aviation Administration (FAA) is proposing to update an existing airworthiness directive for Rolls-Royce RB211-Trent 800 series turbofan engines, requiring the replacement of the fuel-to-oil heat exchanger (FOHE) on these engines, as well as the RB211-Trent 500 and RB211-Trent 700 series engines, to address a risk of engine FOHE blockage.
