Source measurement	When the YOH-4A was eliminated by the Army, Bell went about marketing the aircraft. In addition to the image problem, the helicopter lacked cargo space and only provided cramped seating for three passengers. The solution was a redesigned fuselage, sleeker and aesthetically appealing, adding 16 ft 3 (0.45 m 3 ) of cargo space in the process. A Bell executive contributed to the redesign by drawing two lines on a sketch extending the fuselage to where it meets the tail. The redesign was designated Bell 206A, and Bell President Edwin J. Ducayet named it the JetRanger , denoting an evolution from the popular Model 47J Ranger .^[source]Bell 206 · Development / JetRanger; only the objects and conditions stated in this passage The 206L LongRanger is a stretched variant with seating for seven. The fuselage, stretched a total of 30 inches (760 mm), adds two rear-facing seats between the front and rear seats. Since 1975, Bell has produced more than 1,700 LongRangers across all variants. In 1981, a military version, the 206L TexasRanger was released. The original 206L used an Allison 250 -C20R 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.^[source]Bell 206 · Development / LongRanger; only the objects and conditions stated in this passage In both applications, the 250-C30P is derated from 650 hp for takeoff and 501 hp continuous. The 206L-3 is transmission-limited to 435 hp for take-off, and the 206L-4 is transmission-limited to 495 hp. The derating of the C30P produces an advantage in hot-day and high-altitude operations, as it can produce the rated horsepower at higher altitudes and temperatures where applications that use the maximum rating of the engine at sea level suffer accelerated performance deterioration with increases in temperature and altitude. The 206L-3 and L-4 have not been offered in a twin configuration under those model designations.^[source]Bell 206 · Development / LongRanger; only the objects and conditions stated in this passage In 2007, Bell announced an upgrade program for the 206L-1 and 206L-3 designed to modify the aircraft to the 206L-4 configuration; modified aircraft are designated 206L-1+ and 206L-3+. Modifications include strengthened structural components (including a new tailboom), improved transmission, upgraded engine for the L-1, all of which result in a maximum gross weight increase of 300 pounds and increased performance.^[source]Bell 206 · Development / LongRanger; only the objects and conditions stated in this passage The basic shape and design of the JetRanger remained unchanged since 1967, but Bell introduced the 206B JetRanger II in 1971. In 1977, the 206B-3 JetRanger III was introduced with its modified tail rotor and more powerful engine. 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. On September 1, 1982, pilots H. Ross Perot, Jr. and Jay Coburn departed Dallas, Texas in the " Spirit of Texas ", a Bell 206L-1 (N3911Z).
