|Aviat A-1B Husky|
|Role||Light utility aircraft|
|Design group||Christen Industries|
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.
The Husky has been one of the best-selling light aircraft designs of the last 20 years, with more than 650 sold since production began.
The Husky 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. In 2015 a reversible MT Propeller was approved under a Supplementary Type Certificate for better control during floatplane water operations. The Husky's high power-to-weight ratio and low wing loading result in good short-field performance.
The Husky 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.
The Husky comes in six versions:
- Husky A-1
- Certified on 1 May 1987. Maximum gross weight is 1,800 lb (816 kg). Powered by a Lycoming 0-360-A1P or a Lycoming O-360-C1G of 180 hp (134 kW)

- Husky A-1C-200
- Certified on 24 September 2007. Powered by a Lycoming IO-360-A1D6 of 200 hp (149 kW). The 200 has a gross weight of 2,200 lb (998 kg) and a useful load of 880 lb (399 kg)
Accidents and incidents
- On July 14, 1989 a Husky A-1 operated by the U.S. Border Patrol crashed in flat desert terrain in Arizona while tracking footprints near the U.S.-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." The U.S. Border Patrol eliminated the Husky from its inventory following this accident.
