The Barrows Bearhawk is a family of high-performance, homebuilt aircraft originally designed by Robert Bob Barrows in the early 1990s to fill a utility role beyond typical general aviation designs. It was conceived as a four-seat, heavy-haul, short-field capable aircraft with rugged simplicity at its core. Unlike many certified production aircraft, the Bearhawk is built by amateur constructors from plans or kits, reflecting a long tradition in sport and experimental aviation that values customization and personal craftsmanship. Its versatility and robust design philosophy have allowed the Bearhawk series to evolve into multiple variants including four-seat, tandem two-seat Patrol, side-by-side Companion, Light Sport Aircraft (LSA) and larger capacity models, each tailored for specific missions from backcountry flying to cross-country travel.
Airframe and Structural Design
The Bearhawk’s airframe combines traditional construction techniques with performance-oriented engineering. The fuselage structure is a welded 4130 steel tube framework covered in doped aircraft fabric, providing a durable yet lightweight backbone. The wings are all-metal, typically constructed of 2024-T3 aluminum sheet with hydro-formed ribs and a modified Riblett or NACA 4412 airfoil depending on model and year, striking a balance between low-speed control and efficient cruise performance. This combination of materials gives the Bearhawk remarkable strength and predictable handling across its flight envelope. The high-wing, strut-braced configuration offers excellent downward visibility and clearance for rough field operations, while conventional (taildragger) landing gear enhances its utility in unimproved environments.
General Specifications
For the classic four-place Bearhawk, fundamental dimensions reflect its utility role. The wing spans approximately 33 feet with around 180 square feet of area, optimizing lift and control, especially during slow-flight and short field maneuvers. The overall length is in the region of 23 feet 6 inches, and the cabin is generous for an amateur-built aircraft, measuring roughly 42 inches in width with a substantial baggage compartment extending nearly 10 feet from firewall to baggage bulkhead. These dimensions contribute to the aircraft’s comfortable ergonomics and flexible load distribution. Standard fuel capacity hovers around 50–55 gallons with auxiliary optional tanks increasing range potential. Empty weight typically lies between 1,150 and 1,350 pounds, with gross weights around 2,500–2,700 pounds depending on configuration and equipment choices.
Powerplant and Propulsion
The Bearhawk is engineered to accommodate a broad range of engines within the 150–260 horsepower band for the traditional four-seat models. Common installations include Lycoming four-cylinder and six-cylinder powerplants such as the O-360 and O-540 series, providing reliable performance with simple maintenance. Each builder may select a constant-speed or fixed-pitch propeller tailored to their mission profile and desired cruise/climb characteristics. More recent developments include provisions for fitting alternative engines like the DeltaHawk DHK180 diesel, offering different fuel and performance trade-offs. The flexibility in powerplant choice allows owners to balance cruise speed, climb rate, and fuel efficiency according to personal preferences and mission demands.
Aerodynamic and Flight Performance
Bearhawk aircraft are celebrated for their balanced aerodynamic performance. Cruise speeds for the four-seat Bearhawk generally fall in the 120–150 mph range depending on engine selection and aircraft weight, with never-exceed (Vne) speeds typically near 175 mph. Stall speeds can be impressively low, in the 40 mph neighborhood with flaps deployed, enhancing safety in landing approaches and rough strip operations. Climb rates are equally notable, with typical figures spanning 1,500–1,700 feet per minute at gross weight under optimal conditions. Range varies with configuration and fuel load, with most aircraft achieving anywhere from 650 to 900 miles per full tank setup. These figures underscore the Bearhawk’s utility as both a capable short field performer and a competent cross-country cruiser.
Landing Gear and Ground Handling
The Bearhawk uses a fixed conventional landing gear arrangement, sometimes referred to as a taildragger layout. This setup, combined with large main wheels and optional tundra tyres, suits operations from grass strips, gravel bars, and other unprepared surfaces. The gear is robustly engineered to absorb rough field loads, and many builders equip their aircraft with skis or floats to expand operating environments. Ground handling characteristics emphasize control and stability during taxi, takeoff, and landing phases, making the Bearhawk a favorite among pilots who frequently venture off hard surface runways.
Kit Building and Home Construction
Building a Bearhawk from a kit is a significant yet rewarding project for aviation enthusiasts. Kits are offered with comprehensive airframe components including welded steel parts, aluminum wing structures, fuselage components, hardware, and detailed instructions. Builder skill and tool requirements are moderate, typically involving use of rivet guns, welding equipment for fuselage assemblies, sheet metal brakes, and common hand tools. Estimated completion times vary by kit type, with quick-build options reducing construction hours, while full plans builds can extend into the thousands of hours. The result is a highly customizable aircraft that reflects the builder’s craftsmanship and performance aspirations.
Variants and Evolutions
The Bearhawk family has expanded beyond the original four-place design to include specialized variants. The Patrol model is a tandem two-seat aircraft with a narrower cabin and optimized for utility and bush flying, emphasizing high performance and low stall speeds. The Companion offers a side-by-side seating arrangement for two plus baggage, balancing load-carrying with a more social cockpit layout. Light Sport Aircraft versions target weight and simplicity criteria for LSA certification, appealing to pilots looking for lighter, easier-to-fly options. The line continues to evolve with larger and more capable models that push performance and capacity while retaining the core Bearhawk ethos of rugged utility and pilot-friendly handling.

Legacy and Community
Since its introduction, the Bearhawk has cultivated a loyal following among homebuilders and general aviation pilots worldwide. Aircraft completed by amateur builders operate across multiple continents, demonstrating the design’s adaptability to diverse climates and flying missions. Bearhawk owners often engage in community forums, fly-ins, and knowledge sharing, contributing to a vibrant peer network that helps new builders and pilots maximize the capabilities of their aircraft. The Bearhawk’s enduring appeal lies in its blend of practicality, performance, and the satisfaction of creating a high-utility aircraft with one’s own hands.
