The Avia BH-25 was a biplane airliner built in Czechoslovakia in 1926. Typical of airliners of its time, it seated five passengers within its fuselage, while the pilots sat in an open cockpit above. Of conventional configuration, it was a single-bay biplane of equal span and unstaggered wings, with fixed tailskid landing gear. Originally designed to use a Lorraine-Dietrich engine, this was changed to a Bristol Jupiter in service. After their withdrawal from airline use in 1936, some were used by the military for a while before ending their days as training targets.
