Wassmer Aviation Wa-42 Sancy

Single Piston

The Wassmer WA-42 Sancy is a French four-seat touring aircraft developed in the early 1970s by Wassmer Aviation, a manufacturer known for composite construction techniques. Named after the Puy de Sancy mountain in central France, the WA-42 featured a low-wing configuration with retractable tricycle landing gear and was powered by a Lycoming O-540 engine producing 235 horsepower. The aircraft represented Wassmer's attempt to compete in the high-performance single-engine market alongside American types like the Piper Arrow and Beechcraft Bonanza, offering European pilots a domestically-produced alternative with modern fiberglass construction. Production remained limited, with only a small number built before Wassmer ceased aircraft manufacturing in the late 1970s. The type never achieved widespread adoption, and today represents a rare example of French general aviation design from that era.
