SJ30i / SJ30x
Planned third step in the SJ30 line, after the prototype and the certified SJ30-2; never delivered.
On paper the SJ30i and SJ30x promised midsize-jet speed and range in a light-jet package. In practice neither was certified, none reached a customer, and SyberJet has moved on to the SJ36. Treat this as a jet to watch, not buy.
Buy it if
You follow SyberJet closely, want the fastest single-pilot light jet design around, and would take a rare used SJ30-2 or wait for the SJ36 while the SJ30i and SJ30x remain unbuilt.
Skip it if
You need an aircraft soon, want a factory service network, or regularly fly more than four passengers. The Phenom 300E, Citation CJ4 Gen2 and PC-24 are in production and widely supported.
Biggest compromise
There is no aircraft to buy. The SJ30i flew in 2019 but was never certified, the SJ30x never reached production, and SyberJet's plans now center on the SJ36, targeted for 2032.

SyberJet SJ36
Not yet graded
- SyberJet SJ30-2 instead: The certified version: same airframe, speed and range with the older Honeywell Primus Epic cockpit. Only a handful exist and they rarely change hands.
- Embraer Phenom 300E instead: In production with a worldwide service network, a bigger cabin and an enclosed lavatory, for about 20 knots less speed.
- Pilatus PC-24 instead: Shorter runways, including approved unpaved strips, and a much larger cabin with an enclosed lavatory, trading away speed and some range.

Williams' TAP pay-per-hour plan covers FJ44 engines; enrolled engines get a 5,000-hour overhaul interval instead of 3,500 hours.
Known issues
Never certified or delivered
Neither the SJ30i nor the SJ30x received FAA certification, so no warranty, delivery slot or service history exists.
Single-source parts and support
The SJ30 fleet depends on SyberJet in San Antonio; the only active operator reported parts shortages in 2023.
Tire pressure sensitivity
SJ30-2 tires must stay at 165 psi, plus or minus 2; running low has ruined wheels.
Pre-buy checklist
0 of 8 checked
Factory support for the SJ30 family comes from SyberJet's small San Antonio operation. The Williams engines are widely supported, but airframe parts and training depend on one company.
Review
The full review
Strengths
- Cruises at up to 486 knots, faster than the Phenom 300E or Citation CJ4, and climbs to 49,000 ft.
- About 2,205 nm with four passengers and standard fuel reserves, enough for Southern California to New York in calm air.
- Strong 12 psi pressurization keeps a sea-level cabin to 41,000 ft and about 1,800 ft at 49,000 ft.
Limitations
- Neither version was certified or delivered, so there is no warranty, delivery date or service record to rely on.
- The cabin is 12.5 ft long and 4.4 ft tall, seating four in a club beside a belted toilet seat.
- With full tanks only about 283 lb of payload remains, so maximum-range trips carry a pilot and little else.
The SJ30i and SJ30x were meant to give one of the most unusual light jets ever certified a second life. The SJ30 was designed by Ed Swearingen, certified by the FAA in 2005 as the SJ30-2, and built in tiny numbers by Sino Swearingen and then Emivest Aerospace before production stopped around 2009. SyberJet Aircraft bought the program out of bankruptcy in 2011 and planned two upgrades: the SJ30i, with a new Honeywell-based cockpit called SyberVision and a redesigned interior, and the SJ30x, which added more powerful Williams FJ44-3AP-25 engines, more range and single-point refueling.
Pilot's take
The SJ30 family is built around speed and altitude. The published numbers describe a jet that climbs into the high 40s quickly, cruises in the 470s and 480s, and holds a sea-level cabin well into the 40s, with a single pilot allowed on the certified SJ30-2. The price is a short, low cabin, careful weight planning whenever the tanks are full, and long runways on hot days. The SJ30i's four-screen Honeywell cockpit would have modernized the panel, but without certification it stayed a test aircraft. For now, the SJ30 flying experience lives in a handful of SJ30-2s.
Who this is for
Speed-minded owner-pilots and enthusiasts tracking SyberJet, and buyers who want to understand what the SJ36 builds on. Anyone who needs a jet in service soon should look at a used SJ30-2 or an in-production light jet.
