Development and design

Jack Baumann, who had worked for the Taylor Aircraft Company (later to become

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

, although other sources state that Piper abandoned work on the PA-21 and that the Apache was unrelated. Baumann continued development of the pusher Brigadier, with the second example, the B-290, being fitted with 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. Production at a rate of one aircraft per month was planned for the B-290. The Brigadier was chosen by Willard Ray Custer as the basis of his

Baumann continued to propose more powerful versions of the Brigadier, but no airframes resulted.
