The Bird Wing or later, Bird Wing Imperial was a light sport biplane of the 1920s and 1930s.[1]

Development

The first Bird Wing took McCrum and his assistants 63 days to build at a cost of US$12,000. The prototype flew over 5000 passengers over a period of 15 months. McCrum revised the plans for the Bird Wing again in the 1950s to install a Шаблон:Convert Pratt & Whitney R-985 Wasp Junior radial engine and a 3 inch fuselage widening to convert the design into an agricultural aircraft which never went into production.[2]

Design

The biplane features welded steel tube fuselage with aircraft fabric covering and spruce wood spar wings.[2]

Operational history

Among the many pilots who flew the Bird Wing were Hap Arnold and Charles Lindbergh. McCrum offered comprehensive flight training courses which included flight training in a Bird Wing as well as construction of the aircraft from scratch. The Bird Wing Imperial was tested to meet a 1931 requirement for a United States PT trainer. 50 orders were placed, then canceled at the beginning of the Great Depression.
