The Oskbes Aviatika Mai 920 is a Russian high-wing, cable-braced, single-seat, training glider that was designed and produced by Oskbes MAI Moskau Aviation Institut, first flying in 1992.

Design and development

The 920 was developed from the powered Oskbes Aviatika MAI 890 ultralight, which can also be used to aerotow the 920 glider. The 920 has a 90% parts commonality with the 890. The glider design uses a higher aspect ratio monoplane wing in place of the 890's biplane wing. It is intended to be a simple and robust student solo glider.

The 920 glider is made from aluminium tube and fabric, with the nose cone built from fibreglass. Its 10 m (32.8 ft) span wing is cable-braced from a kingpost. The landing gear is a fixed monowheel gear, with a nose skid or caster and a tail skid.
