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) that is applicable to Sundstrand T-62T-40C series auxiliary power units (APUs). This action requires removal from service of certain compressor wheels in accordance with a drawdown schedule, and replacement with serviceable parts, and establishes a new cyclic life limit for the existing compressor wheels. This amendment is prompted by reports of compressor wheel ruptures. The actions specified in this AD are intended to prevent compressor wheel rupture, which could result in an uncontained APU failure and damage to the aircraft.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
