The Bell 230 is a development of the Bell 222 with newer twin Allison 250 engines and other minor modifications. On August 12, 1991, the prototype 230 took to the skies for the first time. In March 1992, the helicopter received its certification from Transport Canada. November in the same year, delivery of the first production helicopter commenced. In 1995, the production of the Bell 230 ended with a total of thirty-eight helicopters built.
The Bell 230 design incorporates two main rotor blades made of stainless steel fiberglass and elastomeric bearings on the rotor hub that acts as a hinge to flapping, lagging, and pitching motion of the rotor blade.
The helicopter can accommodate up to a maximum of ten persons in flight. Seating layout is available in a standard configuration for seven passengers and a single pilot, or executive configuration of up to six passengers with one to two pilots.
