|37k and 23k photos from Che-22 Amphibian Homebuilt|
Home-built twin-engine parasol flying boat. Aircraft was developed from earlier Che-20. Small underwing floats were replaced by enlarged anhedral wingtip. This became a standard on all following models. In early 90's designers came to manufacturing Che-22 for sale. STOL performance allows to operate even from small forest lakes and rivers and perform variety of tasks:
Che-22 is designed and built in compliance with JAR-VLA, FAR-23 and AP-23 flight standards. It become one of the first Russian homebuilts which is manufactured for common use.
During 5 years Che-22 and its predecessor Che-20 logged about 500 hours of trial and training flights. About 120 pilots were trained. Aircraft evolved from 2-seater powered by 30hp boat engine to 4-seater with pair of Rotax (either 503 or 582) engines. Fuselage is made of epoxy/foam composite sandwich, wings - aluminum with fabric skin. Latest variants have electrically driven gear retraction, mechanical flaps, and an optional BRS 'Cobra' parachute.
Cabin has two removable butterfly-type doors. Basically showed as 2-3 place aircraft (nevertheless may be flown even with 5 men aboard). Windshield may be opened to access the engines while on the water.
Aircraft is available for customers as a 75% pre-assembled kit or as a ready-to-fly aircraft. Two-, three- and four-seat variants with engines (single or two) totaling power from 60hp to 140hp were test-flown and may be delivered. Technical support is (was?) provided by Povolzhski Aviation Science&Technology Center.
As of beginning of 1999 about 30 Che-22 were built and sold mostly in Russia (also 1 was sold to Philippines and then re-sold to Vietnam, one - to South Africa, one - to Ukraina, one - to Greece). Aircrafts can be produced both as pure flying boat and amphibian with retractable gear. BRS can be installed.
