In 1974, the new Bell 222 was announced by Bell. It was the first light commercial twin engine helicopter developed in the United States.
The 222, which first flew on August 13, 1976, incorporated a number of advanced features including dual hydraulic and electrical systems, stub wings housing the retractable undercarriage, and the Noda Matic vibration reduction system developed for the 214ST. Certificated in December 1979, deliveries of the 222 began in early 1980.
The more powerful Bell 222B was introduced in 1982 with a larger diameter main rotor. The 222B-based Bell 222UT Utility Twin, with skid landing gear, was introduced in 1983.
A development of the 222 is the Bell 230, with the 222's LTS 101 engines replaced by two Allison 250 turboshafts, plus other refinements.
A converted 222 first flew as the prototype 230 on August 12 1991. Transport Canada awarded certification in March 1992, and the first production 230 was delivered that November. The 230 had optional skid or wheel undercarriage. Production ended in 1995 with 38 having been built, being replaced in Bell's lineup by the stretched, more powerful Bell 430.
The Bell 222 and 230 are usually flown single-pilot (optional dual controls are available), and can be configured for corporate/executive, EMS or utility transport missions. The aircraft have standard seating for eight, including pilot, in four rows. Alternative seting includes four in main cabin in club configuration.
Engine output is 100% rated at 9598 RPM. Two independent drive shafts deliver power from the engines to the transmission.
The Bell 222's LST-engine exhaust stacks are located at the rear of the engines, while the 230's Allison-engine exhaust stacks are located high on the cowling.
- Two-blade, semi-rigid high-kinetic energy main rotor with preconing and underslinging. The rotor head incorporates elastomeric bearings for hub springs, flapping and pitch change bearings. The system is similar in design to that used by the AH-1 Cobra. Rotor speed at 100% engine speed is 348 RPM.
- All series models incorporate a pusher-type two-bladed tailrotor mounted on the left side of the tailboom, turning at 3396 RPM
- Bell 222
- The original Model 222, sometimes unofficially called a Bell 222A to distinguish it from the Bell 222B. It was powered by two (461kw takeoff rated, 441kW max continuous rated) Honeywell (formerly Lycoming) LTS-101-650C-3 turboshafts.
- Bell 222B
- In 1982 the 222 was given a power upgrade (two 505kW (takeoff rated) Honeywell (formerly Lycoming) LTS-101-750Cs), a larger main rotor, and was renamed the Bell 222B.
- Bell 222UT
- A 222B variant with skids, introduced in 1983.
- Bell D-292
- The Advanced Composite Airframe Program (ACAP) was a 1985 all-composite LHX proof of concept project. The Bell D-292 used the Avco Lycoming engines, transmission, two-bladed main and tail rotors, tailboom, vertical fin, and rotor pylon of the 222. The new airframe used composite materials in place of metal to provide greater strength, lighter weight, lower manufacturing costs, and reduce maintenance costs.
- Bell 230
- In 1991 the 222B design was updated, given more powerful engines, and renamed the Bell 230. Production ended in 1995.
- Bell 222SP
- During the 1990s, a number of 222s were modified to use the 230's Allison engines as an after-market STC due to reliability issues with the Lycoming engines, and redesignated as 222SPs.
- Bell 430
- Bell 430, a stretched 230 (adding another seating row), was launched, with more powerful engines and a four-bladed main rotor. In 1995 the
In addition to the large number of civil operators, a small number of Bell 222 family helicopters have entered military service. One served with Albania from 1979 to 2001.

The Bell 222 is widely known from the TV series Airwolf which featured a modified 222A as the title character.
