About the IAI 1124 Westwind

Type certificated 1976 Source: third-party reference

Overview

The IAI 1124 Westwind is one of the cheapest ways into a mid-size cabin jet, and its used-market price reflects both that appeal and the compromises behind it. Descended from the Aero Commander Jet Commander that IAI bought from Rockwell in 1968, the Westwind is a mid-wing twinjet with large tip tanks, powered by two 3,700 lbf Garrett TFE731-3 turbofans, cruising near 440 KTAS at up to 45,000 ft. The 1124 (Westwind I) and the winglet-equipped 1124A (Westwind II) share the type certificate; the II adds a new wing center-section, more fuel, and higher weights.

For a buyer, the Westwind trades refinement for value. It offers a flat-floor, stand-up mid-size cabin and roughly 2,200 nm of range for less than many turboprops cost, but it is heavy iron to fly, with manual (unpowered) flight controls and a real appetite for runway. It is a mission-first airplane, and its toughness made it a common choice for air-ambulance and maritime-patrol conversions.

Key Features for GA Buyers

Low-cost mid-size cabin: a stand-up, flat-floor cabin and transcontinental-class range for an acquisition price often below a comparable turboprop.
Standard APU: most 1124s carry a Microturbo Saphir APU for cabin climate and engine starting without ground power, unusual at this price.
Special-mission pedigree: the tough airframe and large external baggage bay made the Westwind a frequent air-ambulance and patrol platform, so mission-equipped examples are readily found.

Trade-offs

Runway-hungry: balanced field length often exceeds 5,000 ft, and hot-or-heavy departures need real planning.
Manual flight controls: the Westwind uses unpowered cable-and-pulley controls, so it flies heavier than a modern light jet and asks more of the pilot.
Legacy economics: the TFE731-3 pair burns around 240 gph and the type is old, so engine-program status is the single biggest value swing; an off-program airframe near an inspection carries large reserve risk.
