[edit] Bell 214
Similar in size and apearance to the Bell 205 and Bell 212, the Bell 214 uses a single much larger, 2930shp (2185kW) engine (Lycoming LTC4B-8) and upgraded rotor system giving it a high lifting capacity and good performance at high temperatures and high altitudes. [1] It can be identified by the single large exhaust duct and wide chord rotor blades without stabilizer bars.
- Bell 214 Huey Plus - The prototype 214 flew in 1970. Powered by one Lycoming T53-L-702 turboshaft (1900shp/1415kW). [1]
- Bell 214A/C Isfahan - The 299 Bell 214As for the Imperial Iranian Army Aviation were built beginning in 1972, followed by 39 Bell 214Cs with a hoist and other search and rescue equipment for the Imperial Iranian Air Force. [1]
- Bell 214B BigLifter - Bell offered the Bell 214B "BigLifter" for civil use.[1] Receiving certification in 1976, it was built until 1981 with total production of 104.
- Bell 214B-1 - This version of the Bell Model 214B is able to carry up to 12,500-lb (5670-kg) of internal loads. The external load is the same as the 214B. This was done for certification purposes in some countries where the limit for "heavy" aircraft was/is at 5700kgs. The only difference between the 214B and 214B-1 is the dataplate and the flight manual.
[edit] Bell 214ST
A later derivative, the Bell 214ST (originally "stretched twin", later Super Transporter) was larger and of quite different appearance, with a 17 passenger capacity and two GE CT7-2A engines. This was also intended for sale to Iran, but after the fall of the Shah in 1979, Bell built a total of 100 for other customers. The largest batch of 45 went to Iraq in 1988.[2]
[edit] Present use
An estimated 170 Bell 214A/Cs remain in Iranian service. The overhaul facility set up at the time of delivery, the Iran Helicopter Support & Renewal Company, is now able to do major rebuilds that could be considered manufacture of new machines.
Approximately 24 214Bs are still flying in commercial service where the hook lifting capacity of 8000 lbs suits them for fire fighting, logging, and similar crane work. User countries are Australia (3), Canada (8), France (1), Korea (8), Norway (2), United States (?).
Excluding those in Iraq, about 39 214STs remain in use, some in the service of oil companies where the long range and twin engines are good for off shore work.
