The Federal Aviation Administration (FAA) has issued a new airworthiness directive (AD) for General Electric Company Model CT7-2E1 engines due to a revised analysis showing that a component, specifically the stage 2 turbine aft cooling plate, has a shorter life than previously thought. This directive requires updating maintenance documents by reducing the life limit for this part from 6,100 cycles to 3,100 cycles to prevent potential failures that could result in severe engine and airplane damage. The rule will take effect on April 17, 2025, and affects eight engines currently used in the U.S.
Simple Explanation
The FAA found out that a part in GE engines might wear out faster than they thought, so they are changing the rules to make sure that part is checked and replaced sooner, to keep planes safe.
