The Bell 212 Twin Two-Twelve is a two-bladed, twin-engined, medium helicopter developed from the Bell 205 ( Huey ) powered by a, then revolutionary, Pratt & Whitney Canada Twin-Pac engine made up of two coupled PT6 power turbines driving a common gearbox.

Originally manufactured in Fort Worth, Texas, production was moved to Mirabel, Quebec, Canada in 1988. It has been also built under license in Italy by Agusta as the AB.212

The military version is known as UH-1N ( CH-135 in Canada ) and Agusta also developed a specialized shipborne variant.

Further development of the model 212 led to the Bell 412, the major difference being the composite four-blade main rotor.
