AviPro Aircraft Bearhawk
 
AviproBearcat
 
Designed by Robert Barrows of Fincastle, Virginia, the Bearhawk is a 2 or 4-place design. The design parameter were for a heavy hauling BIG airplane with a good cruise speed and economical operation. Short field performance is excellent with the large flaps. The Bearhawk prototype Bearhawk N6890R is powered by a Lycoming 0-360 (170 hp) set up to burn auto fuel.
The Bearhawk was designed as a personal project by Barrows to carry aircraft engines for delivery as freight for his engine rebuilding business in 1995. It features a strut-braced high-wing with an enclosed cabin 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.

With a 52 inch cargo door, the Bearhawk has a 12 inch C of G envelope. The painted 4130 tube fuselage is ready for covering, giving an actual builders' time of 850-1200 hours. The all metal wings are 90% factory riveted, with solid rivets. Useful load ranges from 1,000-1,300 pounds and can carry four adults and full fuel. The back seat can be removed resulting in a huge cargo area with unobstructed access. Not only does the back seat have its own door, but also the door combines with the cargo door to allow a six-foot loading area.
 
The Bearhawk has an all metal wing with a fabric covered steel tube fuselage and tail feathers. The modified 4412 airfoil combined with big flaps and a long, all metal wing offer the best combination for short field take off and landings.A Cessna windshield, modified lift struts, and the fiberglass nose bowl are some airframe components that need not be built by the homebuilder. The builder time is estimated at 1500-2000 hrs. The Bearhawk kit plane is available in a “quick build” kit. Some Bearhawk owners have put the big tundra tires on their airplanes, and operate on the remote landing spots used by bush pilots in Alaska.
 
The Bearhawk useful load (depending on engine and builder finish out) ranges from 1100-1500 lbs. The 50 USgallon main fuel tanks can be filled and four full sized adults carried with room left over for 250 lbs of baggage or cargo.

The back seat can be removed resulting in a huge cargo area with unobstructed access. Not only does the back seat have its own door, but the back door combines with the cargo door to allow a six foot loading area. In addition, the back seat can be flipped around and mounted with the seat facing aft. This moves the CG of the rear seat passengers 8 or 9 inches forward.

The two prototype Bearhawks (180 hp & 260 hp) have accumulated well over 1000 hours of flight time. There are at least two Bearhawks built by builders with over 700 hours on them.

Introduced in 1995, plans were offered for sale and over 1400 sets of plans have been sold. By November 2012 66 examples had been registered in the United States with the Federal Aviation Administration and seven with Transport Canada. There are over 100 Bearhawks flying in the USA and around the world. The kit only price in 2011 was US$35,295.
 
The plans are now included at no additional cost with the purchase of a full Quick Build kit for the Bearhawk or Patrol.
If less than a full QB kit is purchased, then the plans must be bought from R & B Aircraft (Bob Barrows).

The Bearhawk can be built from plans alone, built from a Quick Build kit made by Bearhawk Aircraft, or some combination of the above. According to Bob Barrows, the QB kit can save up to 70% or more of the time required to build.

The price in 2014 was $295 US for the four place Bearhawk plans. Get a description of the plans or purchase plans online at http://mybearhawk.com/bearhawkplans.html

If less than a full Quick Build kit is purchased, then the plans must be bought from R & B Aircraft (Bob Barrows). The plans are now includedat no additional cost with the purchase of a full Quick Build kit for the Bearhawk or Patrol.

The Patrol version can be built from plans alone, built from a Quick Build kit made by Bearhawk Aircraft, or some combination of the above. According to Bob Barrows, the QB kit can save up to 70% or more of the time required to build.

The price is $280 US for the Patrol plans, and can be paid with a money order, US personal check, Canadian Postal Money Order (US $), or international money order (US $).

Float plane flying customers suggested putting doors on both sides of the Patrol instead of just the right hand side door to allow more flexibility while docking in windy conditions,.  In addition, they requested the fuselages come from the factory with the rear float attach fittings already welded in place. With these suggestions became the Patrol SP (Sea Plane). This model incorporates those two approved design changes; along with some structural strengthening by using thicker wall tubing above the rear float attach fittings.  The price of this full Patrol SP Quick Build kit was US$39,700 in 2014.
