About the Comp Air CA-4

The Comp Air CA-4 is an American amateur-built four-seat composite aircraft designed for homebuilders seeking a roomy, high-performance single. Introduced in the late 1990s by Comp Air Inc. of Merritt Island, Florida, the CA-4 features an all-composite airframe with retractable tricycle landing gear and accommodates a variety of piston engines ranging from 180 to 300 horsepower.

Its spacious cabin and relatively high cruise speeds (typically 160 to 180 knots depending on engine choice) made it popular among builders wanting cross-country capability without the complexity of a twin. The design emphasizes ease of construction with pre-molded fuselage and wing components, though builders still face a multi-year project to completion. While never produced as a certified aircraft, the CA-4 attracted a modest following in the experimental/amateur-built community during the 2000s.

SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
