STC Services


STC's have always been a popular means to upgrade an aircraft to higher performance levels, without purchasing an entirely new aircraft.

The average age of the approximately 250,000 single and light twin-engine aircraft around the world is thirty years old. These conversions allow aircraft owners to upgrade their existing engines and propellers, adding value, performance, and efficiency to their aircraft.
