The Federal Aviation Administration (FAA) has issued a new rule concerning certain CFM International Model LEAP-1A and LEAP-1C engines. This rule stems from investigations following an in-flight incident involving engine failure due to a defective part, specifically the high-pressure turbine (HPT) rotor interstage seal. The directive mandates the removal and replacement of certain HPT rotor interstage seals and prohibits their reinstallation to ensure safety. The rule aims to prevent potential engine failures and maintain aviation safety standards.
Simple Explanation
The FAA is making a new rule because some airplane engines might have a broken part that can cause the engine to stop working during a flight. They want to make sure airplanes stay safe by replacing the broken part and not using it again.
