During the course of 1926,Avia tested the Gnome-
Rhone version of the Bristol Jupiter nine-cylinder radial
air-cooled engine in a BH-21 airframe, and elected to employ this power plant for a new fighter, the BH-33.
This, the last fighter design to be produced by Benes
and Hajn for the Avia concern, was the first Avia fighter
to feature a fixed tail fin from the outset, and commenced
flight trials in 1927. It was ordered into production
for the Czechoslovak air arm with a Walter-built
Jupiter VI rated at 543hp for take-off, armament comprising
two 7.7mm machine guns. A manufacturing licence for the BH-33 was acquired by Poland in 1928,
PZL building 10 pre-production fighters of this type and
PWS building some 50 production examples for the
Polish Air Force as the PWS A from 1930. Three BH-33s
were supplied to Belgium in 1929.
