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.
Simple Explanation
The FAA wants some airplane engines to get a special check-up because they found a mistake in the way a part was made. This check-up is to make sure the engines stay safe and work properly without breaking.
