AVIA BH-33 in Czech and Belgian Service

The Avia BH-33 was a biplane fighter aircraft built in Czechoslovakia in 1927. It was based on the BH-21J which demonstrated promising results by combining the original BH-21 airframe with a licence-built Bristol Jupiter radial engine. Other than the peculiar Avia hallmark of having an upper wing with a shorter span than the lower, it was utterly conventional, even featuring a tail fin for the first time in a Pavel Beneš and Miroslav Hajn design (previous aircraft had a rudder but no fin).

Initial tests of the first prototype were disappointing, displaying performance only marginally better than the BH-21, even when fitted with a more powerful version of the Jupiter. Two further prototypes followed, both designated BH-33-1, each with an increasingly powerful Jupiter variant – one a Jupiter VI, the other a Jupiter VII. The performance of the latter example was finally acceptable for the Czechoslovak defence ministry to order a small production run of only five aircraft.

Three examples were sold to Belgium, where there were plans to build the type under licence, but this did not occur. Licence production was undertaken, however, in Poland, where a single example was sold, along with a licence to build 50 aircraft. These were designated PWS-A and put into service with the Polish Air Force in 1930.
