The IAI Westwind is a business jet initially produced by Aero Commander as the 1121 Jet Commander . Powered by twin GE CJ610 turbojets, it first flew on January 27, 1963, and received its type certification on November 4, 1964, before the first delivery. The program was bought by Israel Aircraft Industries (IAI) in 1968, which stretched it slightly into the 1123 Westwind , and then re-engined it with Garrett TFE731 turbofans into the 1124 Westwind . The 16,800–23,500 lb (7.6–10.7 t) MTOW aircraft can carry up to 8 or 10 passengers, and 442 were produced until 1987.
9-559: The Westwind was originally designed in the United States by Aero Commander as a development of its twin-propeller namesake aircraft , first flying on January 27, 1963, as the Aero Commander 1121 Jet Commander. After successful testing, the aircraft was put into series production with deliveries to customers beginning in early 1965. After initial testing of the prototype, it was modified to production standard with an addition of 2.5 ft to
18-520: A problem, since Rockwell already had an executive jet of its own design, the Sabreliner , and could not keep both in production because of antitrust laws . Therefore, the company decided to sell off the rights to the Jet Commander, which were purchased by IAI in 1968. Jet Commander production amounted to 150 aircraft in the United States and Israel before IAI undertook a series of modifications to create

These included stretching the fuselage and increasing maximum takeoff, maximum landing, and maximum zero-fuel weights, with the wing modified to incorporate double-slotted flaps and drooped leading edges and tip tanks. The trimmable horizontal stabiliser was also modified to have increased span and more travel. Not long after the aircraft went into production, the original General Electric CJ610 turbojet engines were replaced by more fuel-efficient Garrett TFE731 turbofans Numerous airframe modifications also were made, such as drooped leading edges on
45-755: The Westwind as the basis for a maritime patrol aircraft, which became known as the IAI Sea Scan. It had originally been developed to meet a requirement for the United States Coast Guard to replace the Grumman HU-16 Albatross, but they selected the Dassault Falcon instead. In 1980, deliveries of the Model 1124A commenced; modifications included a new wing centre-section and the addition of winglets to

The Jet Commander created
63-460: The rear fuselage, but the wings were mounted halfway up the fuselage instead of the typical low-wing arrangement of aircraft in this class. At FL310 and Mach 0.74 (436 kn; 808 km/h), the 1124 burns 1,600 lb (730 kg) per hour, and 1,200 lb (540 kg) at Mach 0.7 (413 kn; 764 km/h). The 1122 Type Certificate was cancelled, the two airplanes manufactured have been converted to model 1123. The 1124N Sea Scan
72-549: The tips. The revamped aircraft was called the Westwind II, replacing the original design in production. IAI built its last Westwind in 1987, after a total of 442 Jet Commanders and Westwinds had been built, switching production to the Astra . By 2018, 1980s Westwind 1124s were priced from $ 300,000 to $ 700,000. The Jet Commander/Westwind was of broadly conventional business jet arrangement, with two engines mounted in nacelles carried on
81-567: The wings, a dorsal fin, revised engine pylons and nacelles, and further increases in maximum takeoff, maximum landing, and maximum zero-fuel weights. With improvements to a number of onboard systems incorporated, as well, these changes resulted in the 1124 Westwind delivered from 1976. In 1976, in the wake of the terrorist takeover of the Savoy hotel in Tel Aviv, the Israeli Air Force decided to use
