The Baumann Brigadier was a prototype American light transport aircraft of the late 1940s.

[3] His first design for the new company was the B-250 Brigadier, a twin-engined pusher monoplane intended as an executive transport.

An enclosed cabin accommodated a pilot and four passengers, while the aircraft was fitted with a retractable nosewheel undercarriage.

[5] Baumann continued development of the pusher Brigadier, with the second example, the B-290, being fitted with 145 hp (108 kW) Continental C-145 engines but was otherwise similar to the B-250.

The B-290, registered N90616, crash-landed at Pacoima on January 8, 1953, heavily damaging the fuselage and injuring pilot Ward C. Vettel and flight engineer Thomas Cox.
