Bell 427

Encyclopedia : B : BE : BEL : Bell 427

The Bell Model 427 is a twin-engine civil utility helicopter, a derivative of the Bell Model 206-L4 "LongRanger" and Model 407. Like the 407, the 427 uses a 4-bladed rotor system with a rigid, composite rotor hub instead of the 2-bladed conventional rotor of the Model 206. The major difference between the 427 and 407 is the twin engine configuration, versus the single engine of the 407. The 427 offers 8-place seating (two individual seats in the front and a two 3-place bench seats in a club configuration in back) and has systems nearly identical to the 407.

Bell had planned to re-design the 427, offering it in 2004 as the 427i, but later cancelled the program and focused on the improved 429. In February 2005, the existing 60 orders for 427is were converted to the 429.
