69k b/w "History of aircraft construction in the USSR", Vol.1 p.567

Similar in layout to the BICh-7A, the BICh-14 emerged from the wind tunnel trials of the BICh-10 scale model. It was a twin-engine flying wing with retractable landing gear and passenger cabin. Built mostly of wood with fabric skin, duralumin was used on the cabin.

The wing was had three separate sections (central and two outer panels). Four spurs and 60 ribs made the wing structure. Townend ring were installed on the engines, located on the leading edge of the wing.

Aircraft was assembled on Menzhinsky Factory (within TsKB system). First flights by Yu.I.Piontkovsky were performed in late 1934. In 1934 BICh-14 was presented on State Trials at the NII VVS. There it was flown by P.M.Stefanovskij and I.F.Petrov. Stability and control efficiency were found unsatisfactory.

Poor performance was explained by:

Trials continued (as part of experimental program) until 1937.
