The Bell 407 is a four-blade, single-engine, civil utility helicopter; a derivative of the Bell 206L-4 LongRanger. The 407 uses the four-blade, soft-in-plane design rotor with composite hub developed for the United States Army’s OH-58D Kiowa Warrior instead of the two-blade, semi-rigid, teetering, rotor of the 206L-4. The Bell 407 is frequently used for corporate and offshore transport, as an air ambulance, law enforcement, electronic news gathering and movie making. .In 1993, Bell began the development of the New Light Aircraft as a replacement for its Model 206 series.
The Bell 407 features the four-blade main rotor developed for the OH-58D (Model 406). The blades and hub use composite construction without life limits, and provide better performance and a more comfortable ride.
The 407’s fuselage is 8 inches (18 cm) wider, increasing internal cabin space, and includes main cabin windows that are 35% larger. The more powerful Rolls-Royce/Allison 250-C47 turboshaft allows an increase in Maximum Takeoff Weight and improves performance at hotter temperatures and/or higher altitudes. The 407’s airframe is generally similar to the LongRanger, but includes a carbon fiber composite tailboom. The helicopter has standard seating for two crew and five cabin seats.
The 407 was certificated by Transport Canada on February 9, 1996, with the FAA following shortly after on February 23. Full production began in 1996 at Bell’s Mirabel, Quebec, Canada plant and produced 140 airframes in 1997, to fill the initial orders.Bell began deliveries of the 407 in 1996. The 1,000th helicopter was delivered on June 15, 2010.
