The Airworthiness Directive (AD) on Superior Air Parts cylinders
Superior Air Parts and the Aircraft Owners and Pilots Association (AOPA) are working together on an "alternative means of compliance" with the FAA.
Your quick link to the critical information you need about Superior’s engines, parts, and components
From the day we delivered our first valve guide back in 1967, Superior has been focused on two things: making the best FAA-approved PMA parts in the business and providing dealers, technicians and aircraft owners with timely and accurate product information.
Our Technical Support group is totally focused on the second goal. If you cannot find the technical information you need on any of the pages below or have a troubleshooting or service question that is not addressed here, please call: 800.277.5168.
