Model & Market Context
This airframe, registered as N454FX, is a 2015-built Gulfstream GIV-X (G450) with serial number 4339. The aircraft is owned by OLINVILLE PARTNERS A (c/o FLEXJET LLC) and operated under Flexjet-related management out of Cleveland, Ohio, United States.

The cabin of this Gulfstream GIV-X is outfitted in a typical executive configuration accommodating 12–19 passengers in layouts that vary by operator; Flexjet outfitting for this airframe is operator-specific and may differ from the baseline interior. Avionics are reported as Gulfstream PlaneView II, supporting advanced flight management and situational awareness for long-range corporate operations. Typical mission profiles for this airframe leverage its 4,350 nm range and high cruise speed to serve transcontinental and long overwater business sectors from its Cleveland, Ohio operating base. Maintenance considerations are shaped by the twin Rolls-Royce TAY 611-8C powerplants and by corporate upkeep practices under Flexjet stewardship.
The Gulfstream GIV-X (G450) occupies the long-range large-cabin business jet niche, combining high cruise speed and a 45,000 ft service ceiling to enable efficient transcontinental and intercontinental missions. Demand in owner and charter markets favors airframes with modern avionics suites such as Gulfstream PlaneView II, robust twin-engine performance, and operator-managed maintenance programs. For this 2015 airframe (serial 4339), considerations for buyers and charter operators typically include engine time on the Rolls-Royce TAY 611-8C units, interior fitment variability under Flexjet configurations, and the aircraft’s corporate-asset ownership structure. Resale and maintenance planning are influenced by these operator-specific outfitting differences and by the continuing support for the GIV-X family.
