Den Klokke 407 er en firebladet, enmotoret, civil utility helikopter; et derivat af Bell 206L-4 LongRanger. 407 bruger den firebladede, soft-in-plane designrotor med kompositnav udviklet til den amerikanske hærs OH-58D Kiowa Warrior i stedet for den tobladede, halvstive, vaklende rotor i 206L-4.

General Characteristics and Role
The Bell 407 is a versatile, single-engine, turbine-powered light utility helicopter, representing a significant evolution of the Bell 206L-4 LongRanger. Developed by Bell Helicopter Textron, the 407 features a four-bladed main rotor utilizing a composite hub, offering improved performance, ride quality, and speed over the older two-bladed design. The cabin is wider and boasts large windows, making it popular for scenic tours and corporate transport. Its robust performance and reliability have made it a global success, serving a wide variety of roles, including corporate transport, emergency medical services (EMS), law enforcement, electronic news gathering (ENG), and military light observation. It remains a cornerstone of the light helicopter market.
