N3ST

This airframe, registered as N3ST, is a 2014-built Learjet 75 with manufacturer serial number 45-487. It is recorded as owned by SOUTHERN TIRE AVIATION LLC, a corporation based in Columbia, MS, US, and carries a US registration. The aircraft's registry and operator status reflect corporate ownership rather than individual private use, and its estimated market value is $5,495,000, indicating a late-model mid-life appraisal consistent with its year and mission fit. No additional historical transfers or incidents are published in the supplied data.

The cabin of N3ST reflects a typical executive configuration for the model, listed as a 7–8 passenger layout with a forward galley and a belted lavatory, while the overall seating capacity is 12, allowing flexible combinations of passenger seating and belted service/crew positions. Avionics for this airframe are identified as Garmin G5000, consistent with vision flight deck implementations commonly installed on the Learjet 75 family; this fit supports modern cockpit automation and situational awareness for single-pilot or two-pilot operations. Typical missions for this airframe class include high-speed, short- to medium-range corporate shuttle or on-demand charter operations from its operator base in Columbia, MS, US, taking advantage of its transcontinental range capability. Maintenance considerations for this airframe align with twin TFE731 series engine support and Garmin integrated avionics upkeep as part of standard programmatic maintenance cycles.

The Learjet 75 occupies a light to midsize business jet niche, offering high cruise speed (451 kts) and high-altitude capability (service ceiling 51,000 ft) suitable for time-sensitive corporate and charter missions. Competing types in the same market bracket include other light business jets with similar speed and range profiles; buyer and charter demand often favor aircraft with modern avionics suites like the Garmin G5000. Resale and maintenance considerations for this specific airframe include support for Honeywell TFE731-40BR-1 engines and the life-limited components and avionics modernization cycle typical for a 2014-build aircraft. Its listed valuation of $5,495,000 frames expectations for market positioning relative to younger or more heavily equipped airframes.
