General Electric Aircraft Engines Engines
This AD applies to General Electric Aircraft Engines CF34-1A, CF34-3A, CF34-3A2.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to General Electric Company CF34 series turbofan engines, that reduces the allowable operating cyclic life limit for affected fan disks. This amendment is prompted by an updated stress and life analysis. The actions specified by this AD are intended to prevent fan disk rupture, engine failure, and damage to the aircraft.
