Model

The Avia BH-5 was a two-seat sport aircraft built in Czechoslovakia in 1923. It was based on the firm's experience with the BH-1 and shared that aircraft's basic design: a low-wing, braced monoplane. It received the nickname "Boska" due to its registration, L-BOSA, an appellation that was later transferred to the various Avia aircraft derived from this design. The BH-5 was flown competitively by Zdeněk Lhota at the Belgian Touring Aircraft Contest in Brussels in 1923 and won both the overall prize for the event and the King of Belgium Prize. The same year, it won the first prize in its class in the Czechoslovak President of the Republic Competition.

On 1 June 2007, a replica (OK-BOS) built by Marcel Sezemský and members of Historickxˇ letka Republiky ÄŤeskoslovenské completed its first flight from Mladxˇ Boleslav in the Czech Republic. The engine used is an original 1923 Walter NZ_60 five cylinder unit
