The Welch OW-5M (along with the OW-6M, OW-7M and OW-8M) were a family of American two-seat light cabin monoplanes designed by Orin Welch based on his first cabin monoplane design, the ACA Falcon.
Welch's goal was to design cheap and functional light aircraft.
The aircraft is a strut-braced high-wing monoplane with an enclosed cabin with side-by-side seats for two.
The fuselage was constructed with fabric covered welded steel tubing with a triangular cross section.
Total production of all types was 55 aircraft, 35 of which were Continental powered OW-5M models.
