The Zenair Mono-Z CH 100 is a single-seat, single-engined Canadian light aircraft of the 1970s, that was designed by Chris Heintz. It is a smaller version of the Zenair CH 200 with a less powerful engine, which was sold as a homebuilt aircraft by Zenair.

Development and design

After emigrating to Canada and setting up Zenair to sell plans and kits for amateur construction of his Zenith two-seat-light aircraft, the German aircraft designer Chris Heintz started design of a smaller, single-seat development of the Zenith, the Mono-Zenith. ^[1] The Mono-Z CH 100 is similar to the Zenith that preceded it, a low-winged cantilever monoplane of all metal construction. The aircraft features a large cockpit for taller pilots, with a pilot and baggage combined weight allowance of 240 lb (109 kg) and removable wings for storage and towing the aircraft behind a car. The factory claimed a build time of 600 hours. It is designed to be powered by engines from 45 to 100 hp (33.5 to 74.5 kW). ^{[2] [3]}

The first CH 100 made its maiden flight on 8 May 1975, powered by a 55 hp (41 kW) Volkswagen air-cooled engine of 1600 cc, with 110 sets of plans and kits sold by 1982. ^[4] Zenair continued to produce kits until 1988. ^[5]

Operational history

A total of three CH 100s were registered in Canada since 1987 and none are registered in 2010. ^[6]
