N918LL

This entry covers airframe N918LL, a 2009 Gulfstream G450 (GIV‑X) with manufacturer serial number 4177. The airframe is registered in the United States and is recorded as owned by the Delaware corporation SIENNA SERVICES INC of Wilmington, DE; this corporate ownership is the principal recorded operator for the aircraft. The Gulfstream is maintained to typical executive standards for the type and carries an estimated market value of $11,000,000 in current records. Registry data indicating a 22‑seat configuration is a notable detail for this specific airframe relative to more common executive layouts.

The cabin for this specific G450 reflects an atypical registry configuration showing 22 seats, while the manufacturer lists typical outfitting for the model in the 12–16 passenger range; options commonly include forward and aft galley arrangements and forward/aft lavatories. Avionics are recorded as the manufacturer standard PlaneView cockpit, identified as Honeywell Primus Epic / PlaneView, supporting the aircraft’s long-range, high‑speed executive transport role. Operationally, the airframe’s performance figures support transcontinental and intercontinental business missions up to 4,350 nm at cruise speeds near 459 kts and at altitudes up to 45,000 ft. Corporate registration and Wilmington, DE ownership indicate operation under U.S. registry practices with corresponding maintenance and operational oversight.

The Gulfstream G450 (GIV‑X) occupies a performance niche for large‑cabin, long‑range business jets, offering a balance of range, speed and cabin comfort exemplified by this airframe’s 4,350 nm range and 459 kt cruise. Typical competitors include other large‑cabin long‑range types; buyer and charter demand for G450s is influenced by age, avionics fit like Honeywell Primus Epic / PlaneView, and cabin configuration — here notable for its 22‑seat registry. Maintenance and resale considerations for a 2009 airframe such as N918LL include engine program status for the Rolls‑Royce TAY 611‑8C units, systems lifecycle for the PlaneView avionics suite, and market valuation around $11,000,000.
