The Barrows Bearhawk, now also called the Bearhawk 4-Place, is an American amateur-built aircraft, designed by Bob Barrows and produced by R&B AircraftofFincastle, Virginia, AviPro Aircraft and now Bearhawk AircraftofAustin, Texas. The aircraft is supplied as a kit or as plans for amateur construction.[1][2][3][4]
The Bearhawk was designed in the early 1990s[5] 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.[1]
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.[1][4][6]
The prototype was fitted with a 170 hp (127 kW) Lycoming O-360 burning automotive fuel,[3] but in August 2023, the option of fitting the DeltaHawk DHK180 type certified, two-stroke 180 hp (134 kW) diesel engine was added.[7]
By October 2016, 77 examples had been registered in the United States with the Federal Aviation Administration and 11 with Transport Canada.[8][9]
