The Federal Aviation Administration (FAA) has proposed a new airworthiness directive for some Rolls-Royce Deutschland BR700 model turbofan engines due to a manufacturing issue that escaped previous detection. This issue affects the disks in the high-pressure turbine of certain engines, which may fail and cause unsafe conditions if not addressed. The directive would mandate the removal and replacement of the affected disks before they reach a specific number of flight cycles or during the next maintenance visit. This proposed action aims to prevent potential damage and maintain aviation safety.

The Federal Aviation Administration (FAA) issued a new airworthiness directive (AD) requiring certain models of turbofan engines made by International Aero Engines AG to have specific high-pressure turbine (HPT) disks removed from service. This action was prompted by a failure that resulted in high-energy debris escaping an engine, which posed a risk to aircraft safety. The directive is effective January 21, 2021, and it requires removal of the affected parts within 50 flight cycles or 30 days. The FAA determined this rapid action was necessary to prevent potential engine damage or airplane loss.
