Providing Quality STC Products for the Hughes MD 500 Series Helicopter (MD 500E, 520N, 530F)
Leg Fairings and Upper Aft Firewall

Addressing some of the problems we experienced with the 500 series (MD 500E, MD 530F, 520N, etc), 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 1990 with a new name in 2014.
