4-seat general purpose amphibian, designed for off-airdrome operations. Aimed mostly on outdoor travelers and business/service operations, TA-4 may be easily converted into ambulance plane. Air cushion landing gear (tested many times in the USSR, see
Po-2, AIR-?, An-?) allows to use any relatively flat surface for takeoff and landing:
  - short concrete and asphalt strips
  - short strips with no top-soil strength limitations, including grounds with up to 300mm grass height and 200mm hummock height
  - sand strips
  - snow and ice strips
  - water surface of rivers, lakes and sea up to 0.25m wave height, and shoals (up to zero depth)
  - unpaved strips and artificial covering runways in different conditions
  - dry, wet, flooded surface, slush ground, ice-covered and snow-clad surface. The craft is considered among environment friendly vehicles mainly because of the minimization of the negative impact to environment.

TA-4 is a normal high-wing monoplane with T-tail. Pusher engine is installed on the top of the fuselage, right behind the wing. High aspect ratio wing carries flaps and ailerons. For winter operation, aircraft is equipped with de-icing system.
Navigation equipment from Bendix-King allows safe operation over feature-poor terrain and visual takeoff/landing.

In 1990 a single-seat technology demonstrator Poisk (Search) was built. It performed more than 100 takeoffs and landings from various surfaces. In 1991 prototype was presented at SLA-91 Ultra-Light Aviation Show at Chernigov. Success of the Poisk
inspired team to proceed towards final design, but funding was cut in the 1994 and project was frozen.

Recently AKS-Invest enterprise expressed interest in the MiG-TA-4, giving new hope to the project.
