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 certain Textron Lycoming fuel injected reciprocating engines with certain Crane/Lear Romec "AN" rotary fuel pumps installed. This action requires initial and repetitive torque check inspections of pump relief valve attaching screws. In addition, if the torque remains within acceptable values after two inspections, the repetitive torque check inspections may be terminated. This amendment is prompted by reports of inflight engine fires caused by leaking rotary fuel pumps. The actions specified in this AD are intended to prevent rotary fuel pump leaks, which could result in an engine failure, engine fire, and damage to or loss of 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.
