The ANT-43 was a seven-passenger,
low-wing monoplane design of all-metal construction, bearing resemblance to the
Tupolev ANT-31 (I-14) fighter. Intended as an
HQ liaison aircraft, it was conceived using a stencil-based template design method rather than project drawings, and construction of the prototype was undertaken 1935–1936; it was this design method that proved to be the project's undoing. Due to concerns about weaknesses in the ANT-43's airframe construction, when the ANT-43 prototype was completed,
TsAGI summoned a commission led by
Viktor N. Belyayev to decide whether the ANT-43 was fit for flight testing. The commission, deciding that the ANT-43 prototype did not meet structural strength norms, refused to approve flight tests for the aircraft, and the ANT-43 was scrapped without ever being flown. ==Specifications==
