The FAA's summary

This amendment adopts a new airworthiness directive (AD), applicable to Garrett Turbine Engine Company ATF3 series turbofan engines, that requires a one-time inspection for cracks of the curvic and bore area of the high pressure turbine (HPT) rotor assembly disk, and replacement, if necessary, with a serviceable disk. This amendment is prompted by several reports of cracks discovered during routine inspections of HPT rotor assembly disks. The actions specified by this AD are intended to prevent an uncontained failure of the HPT rotor assembly disk.
