Avia BH-9

what is it?

The Avia BH-9 was a twin-seat sports plane built in Czechoslovakia in 1923, based on the BH-5. 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. 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 powerplant.
