The Wassmer WA-51 Pacific is a French four-seat cabin monoplane designed and built by Société Wassmer. Different-powered variants include the Wassmer WA-52 Europa and the Wassmer WA-54 Atlantic.

Design and development

In 1966 Wassmer first flew the WA-50 a prototype glass-fibre single-engined four-seat cabin monoplane with a retractable tricycle landing gear. The design entered production as the WA-51 Pacific with a fixed tricycle landing gear. The low-wing cantilever monoplane was powered by a nose-mounted 150 hp (112 kW) Lycoming O-320-E2A piston engine. A variant, powered by a 160 hp (119 kW) Lycoming IO-320-B1A was called the WA-52 Europa. Further refinements produced the 180 hp (134 kW) Lycoming O-360-A1LD powered WA-54 Atlantic.
