The Tupolev ANT-14 Pravda was a Soviet aircraft, which served as the flagship of the Soviet propaganda squadron. It has been credited as Russia's first all-metal aircraft, with a corrosion-resistant-steel structure.[http://cr4.globalspec.com/blogentry/3944/The-Soviet-Union-s-First-All-Metal-Airplane The Soviet Union's First All-Metal Airplane, globalspec.com]

The ANT-14 was a larger version of the ANT-9, with a 40.4 m wingspan, compared to the 23.8 m span of the ANT-9. Powered by five 358 kW (480 hp) Gnome-Rhône Jupiter 9AKX radial engines, it was capable of carrying a crew of three, as well as 36 passengers, at a maximum speed of 236 km/h (147 mph). However, its cruise speed was only 195 km/h (121 mph). Empty weight was 10,650 kg (23,480 lb) and the maximum takeoff weight was 17,146 kg (37,800 lb). The ANT-14 had a range of 900 km (559 mi), and an operational ceiling of 4,220 m (13,845 ft). It had a non-retractable tailwheel undercarriage whose main gear consisted of dual (fore-aft) wheels.

Operational history

The ANT-14 was tested by Aeroflot in 1932. While these tests revealed no problems with the aircraft, it was far larger than any other aircraft in its fleet, and it had no requirement for an aircraft with a 36-passenger capacity, so no production followed.Duffy and Kandalov 1996, p. 57Gunston 1995, p. 392

On 17 March 1933, the Soviet Union set up an aerial propaganda squadron, named after Maxim Gorky, and the ANT-14 was assigned to it as its flagship, being named Pravda (Truth) after the Soviet newspaper and was used mainly for sightseeing flights over Moscow,the ANT-14 was part of an 18 May 1935 four-airplane flight over Moscow which ended in disaster when an accompanying fighter aircraft maneuvered too close to the Maxim Gorky and struck the airliner's wing, causing it to crash, with 45 fatalities. but did carry out occasional tourist flights to Kharkov and Leningrad (now Saint Petersburg), while it visited Bucharest in 1935 to help celebrate a festival being held there at the time. The ANT-14 carried over 40,000 passengers before being grounded in 1941.Duffy and Kandalov 1996, p. 58
