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. It was the world's first composite material-built aircraft[1].

Design and development

Having manufactured glass-fibre cowlings for Bébé, D112 and D120 Jodels, increasing number of glass-fibre parts for their Javelot, Bijave and Super-Javelot gliders, and then Super-IV aircraft, in 1966 Wassmer first flew the glass-fibre WA-50 prototype, a single-engined four-seat cabin monoplane with a retractable tricycle landing gear. Originally designed as a three-seater powered by a 115cv Potez engine, engine unavailability at the time resulted in a 150cv Lycoming O-320 being used instead and the aircraft becoming a 4-seater[1]. Using the same profile as the Super-IV but only 8.6m span, and compensated with large slotted flaps, the wings were formed from two moulded halves and contained two 70 litre fuel tanks[1]. The fuselage was also manufactured as two halves, and featured butterfly doors.

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.
