The Bell 212 Twin Huey (also known as the Twin Two-Twelve) is a medium civilian helicopter that first flew in 1968. The 212 has a fifteen seat configuration, with one pilot and fourteen passengers. In cargo configuration the 212 has an internal capacity of 6.23 m³ (220 ft3). An external load of up to 5,000 lb (2,268 kg) can be carried.


Based on the stretched fuselage Bell 205, the Bell 212 was originally developed for the Canadian Forces as the CUH-1N and later redesignated as the CH-135. The Canadian Forces took delivery of 50 starting in May, 1971. At the same time the United States military services ordered 294 Bell 212s under the designation UH-1N.

By 1971 the 212 had been developed for commercial applications. Among the earliest uses of the 212 in civil aviation was by Helicopter Service AS of Norway to be used in support of offshore oil rigs. Today the 212 can be found used in logging operations, maritime rescue and resupply in the Arctic on the Distant Early Warning Line or North Warning System.

The 212's main rotor is powered by a PT6T-3 Turbo Twin Pac made up of two Pratt & Whitney Canada PT6T turboshaft engines. They are capable of producing up to 1,342 kW (1,800 shp). Should one engine fail the remaining engine can deliver 671 kW (900 shp) for 30 minutes or 571 kW (765 shp) enabling the 212 to maintain cruise performance at maximum weight.

Early 212s configured with an Instrument Flight Rules (IFR) instrument package were required to have a large and very obvious fin attached to the roof of the aircraft, above and slightly behind the cockpit. This fin was initially determined necessary to alter the turning performance of the aircraft during complex instrument flight maneuvers, but now not required due to revised stipulations of the type certificate. Many aircraft still fly with the modification.

In 1979, with the purchase of eight by the Civil Air Authority, the 212 became the first U.S. helicopter sold in PRC.

The ICAO designator for this aircraft as used in a flight plan is B212.

The Bell 412 is a further development of the Bell 212, the major difference being the composite four-blade main rotor.
