The Avia BH-9 was a single-seat sports plane built in Czechoslovakia in 1923, based on the BH-5.
Avia BH-9
As with other developments in the BH-1 lineage, the BH-9 was a low-wing braced monoplane that accommodated the pilot and passenger in tandem, open cockpits.
Avia BH-11
The BH-9’s structure was strengthened to allow the use of a higher-power engine than in its predecessors, and for the first time, this was a domestically-produced power plant.
Avia BH-11
The Czechoslovakian Army showed interest in it as a trainer and liaison aircraft, and ordered ten examples under the designation B.9.
