Development

Chyetverikov designed and built the TA immediately after World War II, as an amphibious transport, using Duralumin stressed skin construction. The capacious hull had seats for six to eight passengers and room for 1,000 kg of cargo as well as the electrically operated retractable undercarriage which retracted into the sides of the hull vertically. The untapered wing sat atop a short pylon braced by 'N' struts and had electrically operated slotted flaps and fixed floats, as well as the engine nacelles.
The first aircraft was completed in June 1947 and carried out sea and flight trials until the undercarriage collapsed on landing in November 1947, repairs were carried out but the Chyetverikov OKB was closed at the end of, before flight trials could resume.
The second aircraft, designated TA-1, had semicircular wing-tips added, retractable wing-tip floats and area increasing flaps,, as well as other minor changes. Trials were completed and a report submitted by 20 June 1948 but production was not authorised.
The third prototype was completed as the TAF, for use as a reconnaissance or survey aircraft, with greater span, tapered, outer wings. The TAF was flown successfully late in 1948 but the OKB was closed before any further work could be carried out.
