ATEC 122 Zephyr 2000

The ATEC 122 Zephyr 2000 is a Czech ultralight aircraft, designed by Oldrich Olansky and produced by ATEC v.o.s. of Libice nad Cidlinou. The aircraft is supplied as a complete ready-to-fly-aircraft or as a kit for amateur construction.

Design and development
The Zephyr was designed to comply with the Fédération Aéronautique Internationale microlight rules. It features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit under a bubble canopy, fixed tricycle landing gear, a T-tail and a single engine in tractor configuration.

The aircraft's fuselage is made from composites with wooden bulkheads. The semi-tapered 9.6 m span wing is made from plywood with composite spars and leading edges and employs a UA-2 airfoil. The wing is covered with doped aircraft fabric. The standard engine factory-supplied was the 100 hp Rotax 912ULS four-stroke powerplant.

The Zephyr is noted for its low payload. With a useful load of 197.5 kg and full fuel of 43 kg, this leaves only 154.3 kg for occupants and baggage.

The Zephyr was later developed into the ATEC 321 Faeta.
