The Pitcairn PA-1 Fleetwing (Pitcairn Aviation - One) [1] is the first biplane designed for air racing and commercial airmail service by Pitcairn Aircraft Company.[2]
Design
The Fleetwing biplane featured three cockpits capable carrying four revenue sightseeing passengers. The fuselage used (square and round) steel tubing with fabric covering. The squarish fuselage featured a slanted radiator on the front of the lower cowling[3]
Operational history
The prototype PA-1 crashed after a flight with the control cables rigged backwards. A second aircraft was built shortly afterward.[4][5][6]
