The Andreasson BA-4B is a single-seat aerobatic biplane which was marketed for homebuilding and also produced complete.
Andreasson BA-4B Wikipedia
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, equal-bay 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.
In 2014 there were six BA-4Bs on the UK civil register, one Crosby built and the others homebuilt. Three of these have the Continental O-200-A engine but the other three use Lycoming flat fours with outputs between 81 kW (108 hp) and 119 kW (160 hp). In 2009 four BA-4Bs remained on the Swedish register.Andeasson B-4
