Gulfstream G100
The last narrow-cabin Astra: an Astra SPX sold under the Gulfstream name, built by IAI and followed by the wider G150.
The G100 flies farther and faster than most jets at its price, but you sit in a narrow 5-foot-7 cabin, need a long runway, and own one of only 22 built. Buy it for range per dollar, not comfort.
Buy it if
You usually fly two to four people on long trips, want coast-to-coast range and 465-knot speed for under $3M, and your home airport has well over 5,000 feet of runway.
Skip it if
Your passengers want room to move, need bags inside the cabin, or you fly from short runways. A Citation Excel or Hawker 800XP gives more cabin for similar money.
Biggest compromise
The cabin. At 4 feet 11 inches wide and 5 feet 7 inches tall, it is one of the tightest midsize jets, and the bags ride in an outside compartment you cannot reach in flight.

The Astra SPX renamed and supported by Gulfstream.
What changed from the IAI Astra SPX
- Same airplane as the Astra SPX; the Gulfstream name applies from serial 137.
- Same TFE731-40R engines at 4,250 lb thrust each, with unchanged weights and speeds.
- Gulfstream's service centers and parts network took over support from Galaxy Aerospace.
- A Gulfstream-designed interior package was offered on new aircraft.

- Gulfstream G150 instead: The direct successor: a wider, taller cabin and newer cockpit on a similar wing and engines, for a noticeably higher price.
- Learjet 60 instead: Similar speed and a wider cabin from a much larger fleet with easier parts, though range is a few hundred miles shorter.
- Cessna Citation Excel instead: A roomier cabin, much better short-runway ability and a huge service network, in exchange for less speed and range.

Most aircraft for sale have engines on MSP Gold. Major inspection timing runs 5,000 to 7,000 hours, depending on service bulletins.
Known issues
Reverse thrust limited to idle
A permanent rule limits normal reverse thrust to idle, which lengthens stops on wet or short runways and adds brake wear.
Tail attachment fitting history
Past cracks in tail attachment fittings led to inspections and fixes; records must show every required action completed.
Flap and slat drive wear
Flap and slat drive units and flexible shafts are known weak points; review repair history and bulletin status.
Pre-buy checklist
0 of 9 checked
Gulfstream holds the type certificate, and independent shops such as Duncan Aviation work on Astras and G100s. FlightSafety in Dallas runs the only full-motion G100 simulator, so crews travel there for training.
Review
The full review
Strengths
- About 2,700 nm of range with four passengers covers Los Angeles to New York nonstop in still air.
- Cruises near 465 knots with a 45,000-foot ceiling, faster than most midsize jets of its era.
- Public asks of $2.2M to $2.8M buy more range and speed than most jets at that price.
Limitations
- Cabin is 4 ft 11 in wide and 5 ft 7 in tall; most adults cannot stand upright.
- Needs about 5,300 ft of runway at full weight, and reverse thrust is limited to idle.
- Only 22 were built, so some parts take weeks and buyers are few when you sell.
The Gulfstream G100 is the last of a long line of Israeli business jets that began with the 1960s Jet Commander and Westwind. In 2001 Gulfstream bought Galaxy Aerospace, the company selling the IAI Astra SPX, and from serial 137 the same airplane was sold as the Gulfstream G100. Israel Aircraft Industries kept building it until early 2006, and only 22 carry the G100 name. The wider G150 replaced it.
Pilot's take
We see the G100 as a pilot's airplane first. The swept wing and slats give it a broad speed range, and it is comfortable at 41,000 to 45,000 feet where it is most efficient. Expect higher approach speeds than straight-wing Citations and plan runway margins with idle-only reverse thrust in mind. The four-screen Collins cockpit is dated but logical, and an upgraded FMS with WAAS makes it current for most airspace. Crews should budget time in Dallas for training, since that is the only full-motion simulator.
Who this is for
An owner who mostly carries two to four people on long business trips, values speed and range over cabin size, pays a professional crew, and is based at an airport with a long runway.
