Jet Commander 1121 / 1121A / 1121B

Built 1965–1969Out of production2 pilots

The first jet in the family that became the Westwind, Astra and Gulfstream G100 and G150.

43JetGrade70 = typical for light jets

A collector's piece rather than a practical jet. No noise kit exists to meet US Stage 3 rules, so it cannot use airports in the lower 48 states. Only two remain on the US register, and none is offered for sale.

Buy it if

You are a collector or museum that wants the first of the Westwind line, you will base and fly it outside the lower 48 states, and you already have a shop and a parts source lined up.

Skip it if

You need a jet to carry passengers around the United States. Noise rules keep it out of lower-48 airports, and parts for so rare a type increasingly come from salvaged airframes.

Biggest compromise

Legal access. Since January 2016, jets of 75,000 lb or less that do not meet Stage 3 noise standards may not use airports in the 48 contiguous states, except for limited trips such as ferrying for maintenance or export.

  • Cessna Citation I (500) instead: Quieter fan engines, broad parts support and many more examples on the market. Slower, but far easier to own and fly in the US.
  • IAI Westwind 1124 instead: The same family grown up: longer cabin, more range and efficient Garrett TFE731 fan engines, with a much larger fleet still flying.
  • Learjet 24 instead: Another 1960s CJ610 jet, but noise-kitted examples can still use US airports. Smaller cabin, faster climb.

Gold marks the best figure in each row.

What to know before you buy

Engines & inspections

2 × GE CJ610-1 (CJ610-5 on the 1121B) · 2,850 lbf each

No APU

Engine hours until overhaul

0 hr300 hr
  • Stabilizer trim actuator check · 300 hr

No pay-per-hour engine program is offered for these turbojets, so owners fund overhauls themselves.

Known issues

  • Barred by US noise rules

    No Stage 3 noise kit exists, so it cannot use airports in the 48 contiguous states without special FAA permission.

  • Scarce parts

    Most spares now come from dismantled airframes; a missing part can ground the aircraft for a long time.

  • Stabilizer trim actuator directives

    FAA directives require trim actuator checks every 300 hours until a modified actuator is fitted.

Pre-buy checklist

0 of 8 checked

The type certificate sits with Israel Aircraft Industries, now Israel Aerospace Industries. With only a handful left, many parts come from salvaged airframes.

Review

The full review

Strengths

  • The whole cabin sits ahead of the wing and is approved for up to eight passengers, generous for a 1960s light jet.
  • Cruises at roughly 410–435 knots and climbs about 5,200 feet per minute at sea level on two GE CJ610 turbojets.
  • A real piece of history: first flown in 1963, it started the line that became the Westwind, Astra and Gulfstream G100.

Limitations

  • Barred from airports in the 48 contiguous states since 2016 because no Stage 3 noise kit exists for it.
  • Thirsty turbojets burn about 225 gallons an hour, and full tanks leave little weight for passengers.
  • Only two remain on the US register and none is listed for sale, so parts and resale are very limited.

The Jet Commander was Aero Commander's first jet: a straight-wing business jet with room for up to eight passengers that first flew in January 1963 and reached its first customer in January 1965. About 150 were built in three versions. The original 1121 was followed by the 1121A, with more fuel and better wheels and brakes, and the 1121B, with CJ610-5 engines and a stronger landing gear. When Aero Commander's parent company merged with North American Aviation, maker of the Sabreliner, antitrust concerns forced a sale, and Israel Aircraft Industries bought the program in 1968. It grew into the Westwind, then the Astra, and finally the Gulfstream G100 and G150.

Pilot's take

On paper the Jet Commander flies like an honest, heavy straight-wing jet. Plane & Pilot noted that its flight controls are not hydraulically boosted and that in a deliberate stall it does not drop a wing. Aero Commander's 1964 flight-test accounts describe final approaches around 110 knots and touchdowns near 95 knots, gentle numbers for an early jet. The catch is everything around the flying: the CJ610 turbojets are loud and thirsty, parts are scarce, and US noise rules sharply limit where you can take it.

Who this is for

Collectors, museums and enthusiasts who want a piece of business-jet history and can base and fly it outside the lower 48 states, or who plan to display it rather than carry passengers.
