The Bell 407 is equipped with a four-bladed main rotor developed for the OH58D (Model406). The hub and blades without a designated resource are made of composite material and provide the best comfort and other flight characteristics in comparison with previous models. In the design of the main rotor pylon, vibration-isolating means are used, similar means are introduced into the skid landing gear circuit to eliminate resonance at the ground. Compared to the Bell 206, the 407's fuselage is wider by 18 centimeters, which increases the cabin volume. The glazing area is 35 percent larger. The helicopter is powered by a Rolls Royce / Allison 250 C47 turboshaft engine: take-off power 813hp. (606kW.), Maximum continuous power 700hp. (522kW.).

The engine is equipped with a single-channel FADEC type electronic control system. Common stock 477l fuel; in the luggage compartment rear optional extra tank can be placed with a capacity 75l. The engine provides the greatest improvement in take-off weight and the properties at high altitudes and at high temperatures. Glider 407 generally similar in appearance to LongRanger, but it differs from the tail boom, and which is made of carbon fiber. In a typical configuration, the helicopter room for five passengers and two crew members.

Bell in 1995 tested the tail rotor, which is enclosed in a ring, but this idea was subsequently abandoned. Bell engineers also investigated the possibility of mounting two motors on the Bell 407, but instead decided to design a completely new twin-engine helicopter, dubbed the Bell 27. It received two Pratt & Whitney Canada PW206D motors as a power plant.

The Bell 407 helicopter became famous for its record-breaking round-the-world flight, its route passed through the North and South Poles of the Earth. The car with two crew members on board took off from the airport of Fort Worth (Texas) on December 5.12.2006, 23.03.2007 and returned back on March 189, 57900. Within 300 days, more than XNUMX km were covered, a couple of dozen landings were made, even at the North and South Poles. The net flight time was XNUMX hours.
