The Zlin Z 42 is a single-engine two-seat Czechoslovakian trainer aircraft manufactured by Moravan Otrokovice. A developed version, the Z 142, is the most popular aircraft variant in the manufacturer's aircraft line.
The aircraft were built by Moravan Aviation, founded in 1934 by Tomáš Baťa in the Czech Republic.
As a follow-on and replacement for the successful Zlin Trener series of tandem aerobatic trainers, Moravan developed a new family of light aircraft, featuring a side-by-side layout and comprising a two-seat trainer, the Zlín Z 42 and a four-seat trainer/tourer aircraft, the Zlín Z 43. The Z 42 first flew on 17 October 1967, achieving airworthiness certification on 7 September 1970.
The aircraft fuselage center section is of welded steel tube, covered with sheet metal and fiberglass panels. The tailcone is of monocoque construction. The empennage is of sheet metal. The two-spar wings are of all-metal construction. The tricycle landing gear is fixed, with a steerable nose wheel. 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 Z 42 is powered by a Walter inverted six-cylinder engine rated at 134 kW (180 hp).
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 propellor (where the propellor pitch is controlled by the pilot) of the original Z 42. When early Z 42s were refitted with the new propellor, they were redesignated Z 42 MU.
Development continued, with the Zlin 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 6-cylinder, supercharged air-cooled engine of the Z 43 replacing the unsupercharged M 137 engine of the Z 42. The prototype Z-142 first flew on 29 December 1978.
