Airworthiness Directive · Amendment 39-9088 · Precision Airmotive Corporation Appliances
Precision Airmotive Corporation Appliances
This AD applies to Precision Airmotive Corporation Carburetors.
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 certain Precision Airmotive Corporation (formerly Facet Aerospace Products and Marvel-Schebler) Model HA-6 series carburetors, that requires a modification in those carburetors not equipped with a mixture control retainer clip. This amendment is prompted by eight reports of excessive retention screw wear causing rough engine operation or engine power loss on engines equipped with a Model HA-6 series carburetor between January 1986 and August 1992. The actions specified by this AD are intended to prevent the interruption of fuel flow to the engine caused by the mixture control shaft moving out of position because of excessive wear of the mixture control shaft retention screw.
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.
