In early 1927, the Avia company developed a new reconnaissance aircraft based on the BH-26 fighter-reconnaissance aircraft. The Romanian Aviation Ministry was the client for the aircraft, designated BH-28.
Design and Technical Specifications
The prototype first took to the air on February 17, 1927. It was a two-seat, wooden, single-strut biplane, equipped with an Armstrong Siddeley Jaguar radial engine producing 385 hp (287 kW).
The aircraft’s armament consisted of two synchronized forward-firing 7.7mm machine guns and one identical machine gun mounted on a movable turret in the rear cockpit.
Testing and Tragedy in Romania
In April 1927, the prototype was handed over to the Romanian Air Force for testing, during which the aircraft crashed. The crash claimed the lives of pilots Bican and Kinský, winners of the 1926 Coppa d’Italia competition. Consequently, the contract never materialized.
Czechoslovak Competition
The rebuilt BH-28 was then submitted to a reconnaissance aircraft competition held by the Czechoslovak Ministry of National Defense. However, it did not achieve success there either, with the Aero A-32 reconnaissance aircraft being declared the winner.
