The TOM-8 was a prototype Czechoslovak single-engined two-seat training aircraft of the 1950s. It was designed by the VZLU, the Czechoslovak national aeronautic research institute for the Czechoslovak Air Force, with a prototype flying in 1956, but production plans were abandoned in 1960.

Design and development

In the mid-1950s, the Czechoslovak Air Force had a requirement to replace its Aero C-11 trainers, a licence-built version of the Soviet Yakovlev Yak-11. The design of the new aircraft was allocated to a team at the VZLU,[lower-alpha 1], led by Karel Tomáš, who had previously served as chief designer for Tatra's aviation department, and later for Zlín, where he designed the Zlín Z 26 trainer.[2][3]

The resulting design, designated TOM-8 after Tomáš, and also known as the L-8,[3] was a low-winged monoplane of all metal construction,[lower-alpha 2] powered by a single 235 hp (175 kW) Praga Doris C air-cooled six-cylinder horizontally-opposed piston engine. Student and instructor sat in tandem in an enclosed cockpit, with the student in the front seat, and were provided with dual controls. The aircraft had a retractable tricycle landing gear.[5]

The first TOM-8 made its maiden flight on 23 April 1956,[2][3] but development was slowed by engine problems, and plans for production at the Moravan Otrokovice works (where Zlín aircraft were built[6]) were abandoned in 1960.[2]

One TOM-8 is preserved at the Kbely Aviation Museum.[2]
