The Bell 430 is an American twin-engine light-medium helicopter built by Bell Helicopter. It is a stretched and more powerful development of the Bell 230, which, in turn, was based on the earlier Bell 222. The Bell 430 features several significant improvements over the 230, the most significant of these being the new four-blade, bearingless, hingeless, composite main rotor. Although both the 230 and 430 are powered by Rolls-Royce (Allison) 250 turboshaft engines, the 430's engines are 10% more powerful. Other changes include the 1 ft 6 in (46 cm) stretched fuselage, providing for two extra seats, an optional EFIS flight deck, and a choice of either skids or retractable wheeled undercarriage.
The typical configuration seats around 6, including a pilot and co-pilot if desired with 8 passengers in the main cabin behind them in 3 rows of seats. 6- and 8-place executive layouts are offered. In an EMS role it can carry 1 or 2 stretcher patients with 4 or 3 medical attendants, respectively. Maximum external load capacity is 3,500 lb (1,585 kg).
