Aleksandr Yakovlevich Dokuchayev was an aircraft designer and builder in Russia prior to and during World War I.
Most aircraft built by Dokuchayev were modified Farman designs, each unique.
His first aircraft, completed in 1910, was an Anzani-powered biplane of pusher configuration.
In 1912, he completed a sesquiplane version of a Farman IV, and in 1914 he flew another modified Farman type, this time a trainer aircraft with equal span wings and producing 80 hp with its Gnome-Rhone engine.
His fourth model was a return to the sesquiplane configuration, producing a trainer with three rudders operated on skis.
