The Bell 206 is a family of two-bladed, single- or twin-engine helicopters, manufactured by Bell Helicopter at its Mirabel, Quebec plant. Originally developed for the United States Army's Light Observation Helicopter program, the 206 failed to be selected. Bell redesigned the airframe and successfully marketed the aircraft commercially as the five-place Bell 206A JetRanger. The new design was eventually selected by the Army as the OH-58 Kiowa. Bell also developed a seven-place LongRanger, which was later offered with a twin-engine option as the TwinRanger, while Tridair Helicopters offers a conversion of the LongRanger called the Gemini ST. The ICAO-assigned model designation B06 is used on flight plans for the JetRanger and LongRanger, and the designation B06T is used for TwinRangers.


In October 1961, the Army submitted a request for proposals (RFP) for the Light Observation Helicopter (LOH). Bell, along with 12 other manufacturers (including Fairchild-Hiller and Hughes Tool Co. Aircraft Division), entered the competition. Bell submitted their design for Model 206, which was selected out of the design phase as one of three competitors for the flight evaluation. and designated as the YHO-4A.

Bell produced five prototype aircraft in 1962 for the Army's test and evaluation phase. The first prototype flew on 8 December 1962. That same year, all aircraft began to be designated according to the new Joint Services designation system, so the prototype aircraft were redesignated as YOH-4A. Following a flyoff of the Bell, Hughes and Fairchild-Hiller prototypes, the Hughes OH-6 was selected in May 1965.

When the YOH-4A was rejected by the Army, Bell went about solving the problem of marketing the aircraft. In addition to the image problem, the helicopter lacked cargo space and only provided cramped quarters for the planned three passengers in the back. The solution was a fuselage redesigned to be more sleek and aesthetic, adding 16 cubic feet (0.45 m3) of cargo space in the process. The redesigned aircraft was designated as the Model 206A, and Bell President Edwin J. Ducayet named it the JetRanger denoting an evolution from the popular Model 47J Ranger.

206L LongRanger
The 206L LongRanger is a stretched variant with seating for seven (the LongRanger, stretched a total of 30 inches (760 mm), adds two rear-facing seats in between the front and rear seats). Since their first delivery in 1975, Bell has produced more than 1,700 Ls across all variant types. In 1981 a military version was released, the 206L "TexasRanger". The original 206L utilized a Allison 250-C20B engine, and a series of model upgrades replaced this engine with more powerful versions; the 206L-1 used a 250-C28 and the 206L-3 and 206L-4 used the 250-C30P with 490 shaft horsepower.

In 2007, Bell announced an upgrade program for the 206L-1 and 206L-3 which is designed to modify the aircraft to the 206L-4 configuration; modified aircraft are designated 206L-1+ and 206L-3+. Modifications include strengthened airframe structural components (including a new tailboom), improved transmission, upgraded engine for the L-1, all of which result in a max gross weight increase of 300 pounds and increased performance.

Gemini ST and TwinRanger
The TwinRanger name dates back to the mid-1980s when Bell first developed the Bell 400 TwinRanger, but it never entered production

In 1989, Tridair Helicopters began developing a twin engine conversion of the LongRanger, the Gemini ST. The prototype's first flight was on 16 January 1991, while full FAA certification was awarded in November. Certification covers the conversion of LongRanger 206L-1s, L-3s and L-4s to Gemini ST configuration. In mid-1994 the Gemini ST was certificated as the first Single/Twin aircraft, allowing it to operate either as a single or twin engine aircraft throughout all phases of flight.

The Bell 206LT TwinRanger was a new build production model equivalent to Tridair's Gemini ST, and was based on the 206L-4. Only 13 206LTs were built, the first being delivered in January 1994, and the last in 1997. The TwinRanger was replaced in Bell's line-up by the mostly-new Bell 427.

Operational history

The first Model 206A flew on 10 January 1966, and the aircraft was revealed later that month at the Helicopter Association of America (HAA) convention. On 20 October 1966, the JetRanger received full certification by the Federal Aviation Administration (FAA) and delivery of the JetRanger to customers began on 13 January 1967, with the first aircraft being purchased by Harry Holly, president of the Hollymatic Company and previous owner of a Bell Ranger.

The Army eventually selected the 206A in 1968 for use as the OH-58 Kiowa. The United States Navy selected the 206A as its primary trainer the TH-57 Sea Ranger, in 1968, and the Army selected the 206B-3 in 1993, to serve as its primary trainer, the TH-67 Creek. The JetRanger is popular with news media for traffic and news reporting. The LongRanger is commonly used as an air ambulance and as a corporate transport.

The basic shape and design of the JetRanger remained unchanged since 1967, but the 206B "JetRanger II" entered the market in 1971 and the 206B-3 "JetRanger III", with its modified tail rotor and more powerful engine, in 1977. The 206 is flown by a single pilot, who sits in the front right seat.

The Bell 206 was the first helicopter to fly around the world and was piloted by Australian Businessman Dick Smith in 1983. During the trip he landed on container ships at sea to refuel.

On 24 January 2008, Bell Helicopter Textron announced plans to terminate production of the Bell 206B-3 model after current order commitments are fulfilled in 2010.
