The two-bladed, single- or twin-engine helicopters Bell 206 manufactured by Bell Helicopter were originally developed as the Bell YOH-4 for the Light Observation Helicopter Programme of the United States Army. As the model was not selected, it was redesigned and successfully marketed commercially as Bell 206A JetRanger.
The 206L LongRanger is a stretched variant of the Bell 206 Jet Ranger, with seating for seven persons, there were two rear-facing seats in between the front and rear seats added. This variant of the Bell family was very successful and continuously improved (more powerful engines etc.) by the manufacturer.
