Infos techniquesMAI-53 was a cantilever monoplane with a mid-wing design. Fuselage was a welded chrom-steel tube
structurewith longitudinal pine stringers and was covered with canvas. The fuselage had a
triangular cross section with a flat upper face. Wing and tail were a solid wooden construction. In
the landing skid rubber shock absorbers were used and a wheel was installed behind the skid.

The forward-swept wing provided normal vision (for both pilots), improved the gliding properties
and lateral stability for high angle approches to Tushino airfield. Flight tests were conducted by
A. I. Pietsukh. The tests were successful, however a lack of stability and control was observed.
The airframe projected mass was exceeded in production so mass production was abandoned.
Histoire résuméeIn 1953 - 1954 the two-seater training glider MAI-53 was designed and built by the training and production workshop of the aircraft design and engineering department. Chief designer of the airframe was B. N. Sheremetev, chief engineer for the production A. A. Lebedinsky. All design and construction work was done by students under the guidance of E. S. Voigt, I. M. Alyavdin and V. A. Manucharova, teachers of the department. The glider was designed and built under contract with the Central DOSAAF.

The prototype was tested by A. I. Pietsukh at Tusino in the Autumn, 1954. As poor stability and controllability had been noted the tailfin area was enlarged. However as the empty mass exceeded the designed one the type did not go to serial production.
