Engine Conversions

An engine upgrade can breath new life into an aging airframe or transform the performance of an underpowered one. Cascade offers a variety of STC’d engine conversions for agricultural aircraft. Every conversion includes the famous Cascade Pressure Cowl and is delivered as a complete firewall-forward unit for easy installation you can do in your own hangar.
