The IAI Westwind I is the original production model of the Westwind family, developed by Israel Aircraft Industries (IAI) and derived from the earlier Israeli development of the Aero Commander JetStar airframe. First flown in 1963, the Westwind I entered production in 1965 and remained in service until 1978, forming the foundation for subsequent Westwind II and III upgrades.
The Westwind I features a low-wing, twin-engine design powered by two Garrett TFE731-3A turbofan engines, each producing 3,700 pounds of thrust. With a maximum takeoff weight (MTOW) of 23,500 pounds, the aircraft achieves a maximum cruise speed of 455 knots and a range of approximately 2,200 nautical miles. The pressurized cabin typically accommodates up to eight passengers in a business configuration.
Engineering improvements in the Westwind I included a modernized low-drag fuselage, improved avionics over the JetStar, and refinements in wing design for increased efficiency. While avionics were relatively basic by modern standards, the platform established the operational characteristics and performance benchmarks that would guide the evolution of the Westwind II and III models.
As a light business jet, the Westwind I offered operators efficient transcontinental travel with a balance of speed, cabin comfort, and operating economics. It became widely adopted by corporate flight departments and private owners seeking a reliable, early-generation jet with proven performance.
