The Bell Model 407 is a civil utility helicopter, a derivative of the Bell Model 206L-4 "LongRanger". The 407 uses a 4-bladed rotor system with a rigid, composite rotor hub instead of the 2-bladed conventional rotor of the Model 206. The basic systems of the 407 are nearly identical to those in 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.

The Bell 417 was a light helicopter in development by Bell Helicopter Textron. It is single-engine, four-bladed growth variant of the Bell 407, in essesence a civil ARH-70. The 417 was unveiled on February 26, 2006 at the 2006 Heli-Expo, and made its first flight on June 8, 2006 from Bell's XworkX facility.^[1]

Subsequently, the 417 was canceled at Heli-Expo 2007 in Orlando.^{[citation needed]} Production for the civilian version will not happen, but the Military ARH will continue production. This could be caused to Bell's extensive back-order on nearly all of their new helicopters.^{[citation needed]}

The 417 is powered by a Honeywell HTS900 turboshaft engine, producing 970 horsepower and includes full FADEC controls. The cabin will seat 5 passengers in club-seating configuration, in addition to the crew of two.^[2]

Another version, the ARH-70 armed reconnaissance helicopter, is being developed for the U.S. Army.
