STC Products for the Hughes MD 500 Series Helicopter

Addressing some of the problems we experienced 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.

For MD Helicopter repairs and services, please go to Cascade Helicopter Services.

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.
