N404SJ

This entry concerns airframe N404SJ, a 2003-built example of the Sino Swearingen SJ30-2 with serial number 004. The jet was manufactured by Sino Swearingen Aircraft Corp and is registered in the US. Ownership is recorded to ISSO LLC, an LLC based in Cedar City, UT, US, which appears as the current operator/home base on registry records. The airframe is valued at $8,300,000, reflecting its configuration and market position for a single-pilot, seven-seat light business jet of this era.

The cabin in N404SJ is arranged in a seven-place executive layout and the aircraft is certified for single-pilot operation, supporting owner-operator or light charter missions. Typical avionics fit for this airframe follows the SJ30-2 standard with Honeywell Primus Epic equipment, which provides integrated flight management, glass displays and systems monitoring suited to long-range light jet operations. Based from Cedar City, UT, the aircraft’s 2,500 nm range and 436 kt cruise speed enable transcontinental and regional business missions, while the 49,000 ft ceiling offers high-altitude routing and fuel-efficient cruise profiles. Maintenance considerations align with twin Williams FJ44-2A powerplants and the SJ30-2 airframe’s systems; recordkeeping and parts for a serial 004 airframe can affect servicing timelines and operational availability.

The Sino Swearingen SJ30-2 occupies a high-performance light jet niche, offering long range and high cruise speed for its class; with 2× Williams FJ44-2A engines it competes against other long-range light jets in owner-operator and small charter markets. Demand and resale value for a 2003 serial 004 example can reflect the airframe’s avionics fit, single-pilot certification, and maintenance history; the listed value of $8,300,000 positions this airframe within a specific used-market tier where upkeep of Honeywell avionics and Williams engines are primary ownership considerations.
