Superior Aircraft Engine Parts - The FAA has proposed an airworthiness directive (AD) requiring the removal from service of some Superior Air Parts crankshaft assemblies used on all SAP Model IO-360-series and O-360-series reciprocating engines and certain Lycoming engines following three loss-of-
power accidents tied to fatigue cracking of the crankshaft assemblies.

Our goal is not only to help control the cost of replacement parts, but also to deliver the best possible quality and reliability. The proposed AD would permit a one-time special flight permit to fly the aircraft to a maintenance facility to comply with the AD.
Limitations would include no passengers, VFR day conditions only, and avoiding areas of known turbulence. Our FAA-PMA replacement parts and components are manufactured by our global supplier network and are quality controlled to the highest standards in the aviation industry.
Superior doesn't just make "me-too" parts; in many instances they are truly better than original parts. The AD, which affects an estimated 115 crankshaft assemblies installed on U.S.-registered normal-category aircraft, includes Lycoming engine models AEIO-360-, IO-360-, and O-360-series engines if they have a Superior Air Parts crankshaft assembly
with designated part numbers installed. The crankshaft assemblies were installed as original equipment on the affected Superior Air Parts engines and under parts manufacturer approval on the Lycoming engines, according to a notice published January 29.
Comments on the proposed AD may be submitted by March 16 online or by mail to U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE, Washington, DC 20590. Please include Docket No.
FAA-2018-1077 and Product Identifier 2018-NE-40-AD at the beginning of your comments. After investigating three Superior Air Parts crankshaft assembly failures that caused loss of power and "immediate or emergency landings" on March 6, 2017; August 3, 2017;
and October 31, 2018, the FAA "determined that the crankshaft assembly failures resulted from the manufacturing process at [Superior Air Parts'] crankshaft vendor during 2012 and 2014." Analysis determined that all three failures were the result of fatigue cracking, the FAA notice said.
We started by manufacturing one simple valve guide in 1967. Today, Superior Air Parts, Inc., has over 2,000 FAA-approved Parts Manufacturer Approval (PMA) aftermarket replacement parts and components available for Lycoming and Continental piston aircraft engines.
