The Bearhawk 5 is a five-to-six seat American amateur-built aircraft, designed by Bob Barrows and under development by Bearhawk Aircraft. The aircraft is supplied as a kit for amateur construction. [1] [2] [3]
The design was initiated at the request of a friend of Bob Barrows, who was looking for a Bearhawk 4-Place, but with greater capacity. Barrows completed the drawings and the builder started construction of the design, until health issues caused him to abandon the project. A year later, Mark Goldberg, president of Avipro/Bearhawk Aircraft, described the incomplete project to Collin Campbell of Bolivar, Missouri, who was looking for a new building project, after having built several Bearhawk designs in the past. Campbell agreed to complete the prototype and it first flew on 3 May 2020. By 21 May 2020 the prototype had completed five hours of test flying. [1] [2] [3]
Based on the Bearhawk 4-Place Model B, the new design is 2 in (5 cm) wider, with a cabin 14 in (36 cm) longer and an overall length 24 in (61 cm) longer. The stretched cabin permits the installation of a fifth and sixth seat or additional baggage. [1] [2] [3]
The aircraft features a strut-braced high-wing, a five or six seat enclosed cabin accessed by doors that is wide, fixed conventional landing gear and a single engine in tractor configuration. [1] [2] [3]
The fuselage is constructed from welded 4130 steel tubing covered with doped fabric, while the wings are constructed from riveted aluminum sheet. [4] The wings are identical to the Bearhawk 4-Place Model B, employing the same Riblett 30-413.5 airfoil [5] and mounting flaps. [4] The aircraft's recommended engine power range is 250 to 315 hp (186 to 235 kW) and standard engines used include the 250 hp (186 kW) Lycoming O-540, although the recommended engine is the 315 hp (235 kW) Lycoming IO-580 four-stroke powerplant. [1] [2] [3]
The test pilot, Rollie van Dorn, noted, "the Bearhawk Model 5 offered no surprises on takeoff or climb out. With all that power, things happen quickly." [3]
As of December 2023, the prototype and three kit built examples have been registered in the United States with the Federal Aviation Administration. [6]
In an extensive flight review in December 2020, AVweb writer Paul Dye note of its flight characteristics, "you’re obviously not going to mistake the Bearhawk 5 for a single-seat acrobatic machine, but both roll and pitch forces were surprisingly light for an airplane of this size. Rudder was appropriate and positive, and all three axes were harmonious enough to easily fly the airplane in formation with no prior practice. Of course, when working in formation, nothing is better than an excess of power for rapid acceleration when you need to pull forward (coupled to a constant-speed prop that slows you down quickly when you need to back up in a hurry), and the Bearhawk 5 has plenty of extra power. The three-blade Hartzell does a great job of turning that power into both acceleration and deceleration, so the package works pretty well." [7]

The American Champion 8KCAB Decathlon and Super Decathlon are two-seat fixed conventional gear light airplanes designed for flight training and personal use and capable of sustaining aerobatic stresses between +6g and −5g. The Decathlon entered production in the United States in 1970 as a more powerful and stronger complement to the American Champion Citabria line of aircraft.
The Van's Aircraft RV-10 is a four-seat, single-engine, low-wing homebuilt airplane sold in kit form by Van's Aircraft. It is the first four-seat airplane in the popular RV series. The RV-10 first flew on 29 May 2003, and the first kit parts were delivered to a customer in September 2003.

The Colonial Model C-1 Skimmer was an American small single-engined amphibian flying boat built by the Colonial Aircraft Corporation. It was the start of a line of very similar aircraft designed by David Thurston.
The Spencer Amphibian Air Car is an American light amphibious aircraft. The name was first used in 1940 for a prototype air vehicle that developed into the Republic Seabee. The name was later used by its designer Percival Spencer for a series of homebuilt amphibious aircraft roughly based on the Seabee design.
The American Legend AL3, AL11, and AL18 are a series of American light-sport aircraft inspired by the Piper Cub family.

The Socata TB is a series of light single-engine piston aircraft developed and manufactured by French aircraft company SOCATA. The letters TB within the designation stand for Tarbes, the French city where the aircraft series is manufactured. The TB series planes have come to be known as the "Caribbean Planes" due to the island naming convention adopted for the various models, though they are not often seen flown in that region.
