Wencor Group


Providing TRUE Reliability for Over 25 Years

Accessory Technologies Corporation

Accessory Technologies Corporation (ATC) is a globally recognized FAA and EASA repair facility with a long history of providing exceptional quality and service dating back its inception in 1997.

The primary focus of ATC is Pneumatics and Actuation systems, resulting in the development of numerous product improvements for various components. Working closely with its customers, ATC has identified parts with a high frequency of failure modes, ultimately creating true build standards which improve on-wing reliability. Customers who have benefitted from this are FedEx, UPS, United and many other commercial airlines.

ATC became part of the Wencor Group in 2017, enabling them to offer these build standards and workmanship at a lower cost to the operator through the use of PMA’s. In some cases improved PMA’s are integrated to further enhance the on-wing times, often measuring on-wing time in years, not months. In 2020, ATC opened a 30,000 square foot state of the art facility in Edgewood, New York, and expanded its’ capabilities to include the service of High Flow valves and Air Turbine Starters, for which Wencor owns over 200 combined PMA parts that can be incorporated. As a solutions-minded business partner, ATC prides itself in improving component reliability and providing cost savings to its customers.


ATC is committed to providing each customer with the highest level of quality service.

Accessories Technology Corporation is a member in good standing of the Aeronautical Repair Station Association.
