Cascade Airframe Repair, Inc. was established in 1975 to provide quality service and repairs on Hughes / MD 500 series helicopters. Addressing some of the problems we experience with the 500 and 500n series we developed, STC’d replacement landing gear leg fairings and an upper aft firewall.

​

The Cascade Airframe Repair, Inc. name listed on the original STC’s has changed to Cascade STC LLC. The same great parts as originally certified in 1988 with a new name in 2014.

​

With over 39 years of experience working on the Hughes / MD 500 series helicopters, Cascade STC provides high quality STC parts and service that the helicopter industry can trust and depend on.
