The Andreasson BA-4B is a single-seat aerobatic biplane which was marketed for homebuilding and also produced complete.
The BA-B4B was based on Andreasson's 1944 wooden BA-4 revised to take advantage of more modern construction techniques, such as the use of sheet metal. The first example was built by apprentices at the Malmö Aircraft Industry (M.F.I.). It is a single-bay, staggered-wing biplane with fixed tailwheel undercarriage. P.J.C Phillips acquired worldwide production rights for complete, rather than kit built, version and marketed them in the UK through Crosby Aviation. In the US the B-4B was marketed by Larry Karp as the Canary Hawk.
