About the Bell 407

The Bell 407 is one of the world's most successful single-engine light utility helicopters, combining the proven dynamics of the iconic Bell 206 JetRanger with a modern four-blade composite rotor system and a more powerful Rolls-Royce 250-C47B turboshaft engine. First flown in 1994 and certified in 1996, the 407 was designed to bridge the gap between the smaller JetRanger and the twin-engine 412, offering significantly improved performance, reduced vibration, and a quieter cabin while retaining single-pilot certification and relatively low operating costs. Its spacious cabin seats up to six passengers plus pilot, and the type quickly became a favorite for corporate transport, emergency medical services, law enforcement, and utility operations worldwide.

The 407's four-blade rotor system, derived from the Bell 412, delivers exceptional hover performance and hot-and-high capability, with a service ceiling of 20,000 feet and a cruise speed around 120 knots. The helicopter's versatility is reflected in its operator base: it serves equally well as an air ambulance in urban environments, a patrol platform for police agencies, a VIP shuttle for executives, and a workhorse for ranchers and utility companies in remote terrain. Bell has delivered over 1,400 units since production began, with the type operating on every continent except Antarctica.
