The Barrows Bearhawk is an American amateur-built aircraft, designed by Bob Barrows and produced by R&B Aircraft of Fincastle, Virginia, AviPro Aircraft and now Bearhawk Aircraft of Austin, Texas. The aircraft is supplied as a kit or as plans for amateur construction.
Design and development
The Bearhawk was designed as a personal project by Barrows to carry aircraft engines for delivery as freight. It features a strut-braced high-wing a four seat enclosed cabin that is 42.5 in (108 cm) wide and accessed by doors, fixed conventional landing gear and a single engine in tractor configuration.
The aircraft fuselage is made from welded steel tubing covered in doped aircraft fabric, while the wings are made from aluminum sheet. Its 33 ft (10.1 m) span wing employs a NACA 4412 mod airfoil, has an area of 180 sq ft (17 m2) and mounts flaps. The aircraft's recommended engine power range is 150 to 260 hp (112 to 194 kW) and standard engines used include the 180 hp (134 kW) Lycoming O-360 and 250 hp (186 kW) Lycoming O-540 four-stroke powerplants. Construction time from the supplied kit is 1200 hours.
