In the late 1950s Piper started to design a two-seat (side-by-side) low-wing monoplane trainer built of fibreglass reinforced plastic construction. Originally intended to be powered by a 100 hp (75 kW) Continental O-200 engine, the prototype instead used a 108 hp (81 kW) Lycoming O-235-CIB piston engine. The prototype, registeredN2900M first flew in 1962 but the type did not enter production. The Papoose prototype was on "permanent loan" to the EAA Museum at Oshkosh from 7/17/1973 until 6/25/1987 when it was returned to Lock Haven. It currently resides in the Piper Aviation Museum in Lock Haven.
