Björn Andreasson BA-4B SE-XCA
Photographed at Svedinos Bil och Flygmuseum, Ugglarp, Sweden on 21 July 2011.
This is a single-seat aerobatic biplane marketed for homebuilding. It is based on Andreasson's pre-war BA-4 Midget of 1944, revised to take advantage of more modern construction techniques, such as the use of sheet metal in place of the original's all-wood structure. It is a single-bay, staggered, equal-bay biplane with fixed tailwheel undercarriage. It was offered in the UK by Crosby Aviation and in the US by Larry Karp as the Canary Hawk.
The aircraft photographed here was c/n 2, home-built in 1965 by Tage Simonsson, at that time employed as a pilot and technician by Svensk Flygmotor AB at Trollhättan. It flew for the first time on 10 July 1968, with a 100 hp Continental O-200 engine. Tage and his son Leif showed it off at many displays, and it was gradually modified, with increasingly more powerful engines, 130, 160 and 180 hp. Although shown here suspended upside-down at Svedinos, it was missing today when I visited the Museum, and Museum owner Björn Svedfeldt explained that the owner had retrieved it do "do some more flying"!
There are several BA-4Bs extant on the UK register.
