Bell 407: 161 mph, 6 Passengers & Light Utility Helicopter Specs
1. Overview
The Bell 407 is a single-engine, light utility helicopter developed by Bell Helicopter as the successor to the legendary Bell 206 JetRanger. First flown in 1994, the 407 entered service in 1996 and has since become one of the most popular helicopters in its class, with over 1,500 aircraft delivered worldwide. Combining the proven dynamic components of the OH-58D Kiowa Warrior with a modern four-bladed rotor system, the 407 offers exceptional performance, reliability, and versatility.
The 407 was developed to meet the need for a light helicopter with improved payload, speed, and comfort compared to the 206. The four-bladed rotor system reduces vibration and noise while improving lift and maneuverability. The spacious cabin accommodates up to six passengers in club seating, with large windows providing excellent visibility. The aircraft is certified for single-pilot IFR operations and can be equipped with a wide range of mission-specific equipment.
The aircraft's name "407" continues Bell's numerical designation system. The Bell 407 serves in a wide variety of roles, including corporate transport, utility, law enforcement, air medical services, and military training. With its combination of performance, reliability, and low operating costs, the 407 has become a favorite among commercial operators and private owners worldwide. The 407GXi variant, introduced in 2016, features a more powerful engine and advanced avionics, ensuring the type remains competitive through the 2030s.

3. Velocity Engineering
The Bell 407's aerodynamic design builds on the proven JetRanger platform while incorporating modern improvements. The four-bladed, soft-in-plane rotor system provides 30% more lift than the 206's two-bladed rotor while significantly reducing vibration. The composite rotor blades feature advanced airfoils and blade twist that improve hover efficiency and high-speed performance. The rotor head uses elastomeric bearings that eliminate lubrication requirements and reduce maintenance.
Power comes from a Rolls-Royce M250-C47B turboshaft engine on the 407GXi, producing 650 shaft horsepower at takeoff. The M250 is one of the most successful helicopter engines ever built, with over 30,000 produced and 200 million flight hours accumulated. The engine is FADEC-controlled, automatically managing power to reduce pilot workload and ensure optimal performance. The engine's modular design simplifies maintenance and reduces downtime.
The flight control system is conventional hydromechanical with hydraulic boost. The aircraft handles like a light helicopter, with responsive controls and excellent stability. The rotor brake stops the rotors quickly after shutdown, and the blades can be folded for compact storage. The 407's maximum speed of 161 mph is among the highest in its class, achieved through careful aerodynamic refinement and powerful engine.
The 407's performance enables operations from confined areas and high-altitude airports. The aircraft can hover out of ground effect at 10,000 feet on a hot day, making it suitable for mountain operations. The range of 360 nautical miles allows non-stop flights between most city pairs, and the aircraft's all-weather capability ensures operations in marginal conditions.
4. Systems & Technology
Garmin G1000H NXi Glass Cockpit: The 407GXi features the most advanced avionics suite in its class. The G1000H includes three large displays, with synthetic vision, terrain awareness, traffic collision avoidance, and weather radar. The system is fully integrated with the aircraft's engine and flight controls, enabling coupled instrument approaches and automatic flight path management. The touchscreen interface reduces pilot workload and improves situational awareness.
Cabin Comfort: The 407's cabin is designed for passenger comfort on short to medium flights.

6. Performance Analysis
Bell 407 vs Bell 206 JetRanger: The 407 represents a 30% performance improvement over the 206. It carries 50% more payload (2,500 lb vs 1,500 lb), is 20% faster (161 mph vs 130 mph), and has 30% greater range (360 nm vs 275 nm). The four-bladed rotor reduces vibration by 50%, improving passenger comfort and reducing pilot fatigue. The 206 remains in service with many operators, but the 407 is the preferred choice for new aircraft.
Bell 407 vs Airbus H125: The H125 (formerly AS350 Écureuil) is a direct competitor in the light single-engine market. The H125 has slightly higher payload (2,600 lb vs 2,500 lb) and better hot/high performance, but the 407 has a more spacious cabin and lower operating costs. The H125's three-bladed rotor is simpler but produces more vibration than the 407's four-bladed system. Both are excellent aircraft; the choice depends on operator preference and mission requirements.
Bell 407 vs MD 600N: The MD 600N features the NOTAR (no tail rotor) system, which eliminates the tail rotor for improved safety. The 407 has better payload and range, while the MD 600N has lower noise and better safety in confined areas. The 407's lower acquisition cost and wider support network make it more popular with commercial operators.
7. Light Utility Excellence
The Bell 407 represents the state of the art in light utility helicopters. For over 25 years, it has been the preferred choice for operators who need a reliable, efficient, and versatile helicopter for a wide range of missions. Its combination of performance, comfort, and operating economics has made it a favorite among corporate flight departments, utility operators, and government agencies worldwide.
The 407's success stems from its thoughtful design and continuous improvement. The basic airframe—with its four-bladed rotor, spacious cabin, and powerful engine—proved so sound that it has accommodated 25 years of upgrades. The 407GXi, with its modern avionics and more powerful engine, is significantly more capable than the original 407, yet it retains the same handling characteristics and reliability that made the type famous.
For the pilots who fly it, the 407 is a joy to operate. The responsive controls, powerful engine, and smooth rotor system make it one of the best-flying helicopters in its class. The modern avionics reduce workload and improve safety, especially in instrument conditions. The spacious cabin keeps passengers comfortable and happy, enhancing the value of the aircraft for corporate and charter operators.
As the 407 enters its third decade of production, its future is bright. The helicopter will continue to be produced for years to come, serving customers around the world in roles ranging from corporate transport to air ambulance to utility work. For the operators who depend on it, the 407 is more than a machine—it's a trusted partner that gets the job done, day after day, year after year.
