The inverted inline engine was replaced with a four-cylinder horizontally-opposed Lycoming IO-360 engine. In the late 1980s, further development work was initiated. The prototype Z-142 first flew on 29 December 1978. ĭevelopment continued, with the Zlín Z 142, featuring a slightly enlarged two-seat airframe based on that of the Z 42 and the more powerful (157 kW (210 hp)) Walter (now LOM) M 337 fuel-injected inverted six-cylinder, supercharged air-cooled engine of the Z 43 replacing the unsupercharged LOM M137 engine of the Z 42. When early Z 42s were refitted with the new propeller, they were redesignated Z 42 MU. The revised Zlín Z 42M flew in November 1972, with a revised tail taken from the Z 43, and a Constant speed propeller replacing the variable pitch propeller (where the propeller pitch is controlled by the pilot) of the original Z 42. The Z 42 is powered by a Walter inverted six-cylinder engine rated at 134 kW (180 hp).

Designed for aerobatics instruction, it was certified to +6.0 and -4.0 limit maneuvering load factors, and was equipped with full inverted fuel and oil systems, permitting extended inverted flight. The tricycle landing gear is fixed, with a steerable nosewheel. The two-spar wings are of all-metal construction. The tailcone is of monocoque construction. The aircraft fuselage center section is of welded steel tube, covered with sheet metal and fiberglass panels. The Z 42 first flew on 17 October 1967, achieving airworthiness certification on 7 September 1970. The aircraft were built by Moravan Aviation, founded in 1934 by Tomáš Baťa in Czechoslovakia.Īs a follow-on and replacement for the successful Zlín Trener series of tandem aerobatic trainers, Moravan developed a new family of light aircraft, featuring a side-by-side seat layout, and comprising a two-seat trainer, the Zlín Z 42 and a four-seat trainer/tourer aircraft, the Zlín Z 43. Zlín Z 42M, tail number SP-AKE (nr 0170).
