About Cascade STC

Our Story

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.
