The Bearhawk LSA is an American amateur-built light-sport aircraft, designed by Bob Barrows and produced by Bearhawk Aircraft of Austin, Texas. The aircraft is supplied in the form of plans or a kit for amateur construction.

The aircraft was introduced to the public at AirVenture 2012.

Design and development

The Bearhawk LSA is a "clean sheet design" inspired by the larger Barrows Bearhawk. The LSA features a strut-braced high-wing, a tandem enclosed cockpit accessed by doors, fixed conventional landing gear and a single engine in tractor configuration. The cockpit is 31 in (79 cm) wide. In 2015 a quick-build kit was introduced at the U.S Sport Aviation Expo.

The aircraft fuselage is fabricated from welded 4130 steel tubing covered in doped aircraft fabric. The aluminum structure wing, covered in flush riveted aluminum sheet, employs a new Harry Riblett-designed airfoil and does not have flaps. The wing is supported by a single strut per side. The engine power range is 65 to 100 hp (48 to 75 kW) and the recommended engines include the 65 hp (48 kW) Continental A-65, 75 hp (56 kW) Continental A-75 and the 100 hp (75 kW) Continental O-200 four-stroke powerplants.

The aircraft was designed for a maximum gross weight of 1,500 lb (680 kg) in the utility category, but is limited to 1,320 lb (600 kg) in the US light-sport aircraft category.

Operational history

As of February 2016, four examples were registered in the United States with the Federal Aviation Administration.
