N51GS

This airframe, registered as N51GS, is a 2013-built Learjet 45 with manufacturer serial number 466. It is owned by General Shale Building Materials Inc., a corporation based in Johnson City, TN, US, and operates on the US civil registry. The airframe's documented history centers on corporate ownership and operation for business transport; notable registry actions are limited to its active corporate registration. Condition and valuation details are not published in the provided data.

The registry lists 12 seats for this airframe, while typical Learjet 45 executive interiors usually accommodate 6–9 passengers in dedicated executive layouts; this suggests the installed cabin for N51GS may be configured for higher passenger density or ferry/utility roles relative to typical opulent executive fit-outs. Avionics for the airframe are recorded as a Honeywell Primus 1000 four-tube EFIS or the typical Honeywell Primus suite used on Learjet 45s, supporting modern flight management and glass cockpit instrumentation. Operated by a Johnson City, Tennessee-based corporation, typical missions would include regional business transport and point-to-point executive travel within the aircraft’s 2,120 nm range and high-speed cruise at 457 kts, benefiting from the model’s long-range light-jet capability. Maintenance considerations align with multi-engine fixed-wing corporate operations and Honeywell TFE731-series engine support programs.

The Learjet 45 family occupies the light-to-midsize business jet niche, offering high cruise speeds and a 51,000 ft service ceiling suited to fast cross-country travel. Competing models in its class include other light to midsize business jets that balance speed, range, and cabin size; buyer and charter demand typically favor well-equipped, low-time airframes with updated avionics such as the Honeywell Primus suite. Resale and maintenance considerations for this 2013 airframe include lifecycle support for the TFE731-40 engines and avionics modernization potential, factors that influence marketability for corporate operators and charter fleets.
