Aviat Husky
The Aviat Husky is a two seat, high wing, utility light aircraft built by Aviat Aircraft of Afton, Wyoming.[2]
It is the only all-new light aircraft that was designed and entered series production in the United States in the mid to late 1980s.[2]
Development
Design work by Christen Industries began in 1985. The aircraft is one of the few in its class designed with the benefit of CAD software. The prototype first flew in 1986, and certification was awarded the following year.[2]
The Husky has been one of the best-selling light aircraft designs of the last twenty years, with more than 650 sold since production began.[1]
Design
The plane features a braced high wing, tandem seating and dual controls. The structure is steel tube frames and Dacron covering over all but the rear of the fuselage, plus metal leading edges on the wings. The high wing was selected for good all-around visibility, making the Husky ideal for observation and patrol roles. Power is supplied by a relatively powerful (for the Husky's weight) 180 hp (134 kW) Textron Lycoming O-360 flat four piston engine turning a constant speed propeller. The Husky's high power loading and low wing loading result in good short-field performance.[2]
Options include floats, skis and banner and glider tow hooks.[2]
Operational history
The aircraft has been used for observation duties, fisheries patrol, pipeline inspection, glider towing, border patrol and other utility missions. Notable users include the US Department of the Interior and Agriculture and the Kenya Wildlife Service, which flies seven on aerial patrols of elephant herds as part of the fight against illegal ivory poaching.[2]

Accidents and incidents
- On 14 July 1989 a Husky A-1 operated by the U.S. Border Patrol crashed in flat desert terrain in Arizona while tracking footprints near the US-Mexican border, killing the pilot. The aircraft was flying with flaps set at 20 degrees, while the pilot operating handbook recommends 30 degrees for all maneuvering with flaps extended and indicates that a loss of altitude of 150 feet can be expected in a power-off stall condition. The US National Transportation Safety Board determined the cause of the accident to be "failure of the pilot to maintain adequate airspeed, which resulted in a stall. The lack of altitude for recovery was a related factor."[6][7] The U.S. Border Patrol eliminated the Husky from its inventory following this accident.
