The airframe bearing tail number N342SG is a 2002-built Learjet 45 with serial number 231, currently registered in the United States as a fixed-wing multi-engine aircraft. The listed owner is MHS 3-2-1 GO LLC (an LLC based in Saint Louis, MO, US), and the aircraft’s documented valuation is $2,272,500. Registry and ownership details identify it as an operator-backed business jet typically based from its owner's locale; registration and ownership records reflect operation under the named LLC. No further public record of prior operators or notable incidents is provided in these data.

The cabin of this specific Learjet 45 is laid out in a typical double-club configuration providing executive seating for 8–9 passengers within a flat‑floor cabin, supplemented by a forward galley and an aft lavatory; overall seating capacity is 12. The installed avionics package is the Honeywell Primus 1000 four-tube EFIS, with common fit items including dual UNS-1Ew FMS, TCAS II, and EGPWS, enabling conventional point‑to‑point business missions and single-pilot or two-pilot operational profiles depending on operator standardization. With a long-range cruise speed of 445 kts and a maximum practical ceiling of 51,000 ft, this airframe is typically employed on corporate transfer, on-demand charter, or owner-operator executive transport missions flown from its owner’s Saint Louis, Missouri base. Maintenance considerations for this individual aircraft align with Honeywell TFE731-20 engine support and avionics upkeep consistent with the Primus 1000 suite.

As a member of the Learjet 45 family, this airframe occupies a light-to-medium business jet performance niche characterized by high-speed cruise and a transcontinental range near 1,968 nm. Competing models in the same capacity commonly emphasize similar cruise speed and cabin layouts; buyer and charter demand for this configuration centers on operators seeking fast point-to-point capability with a compact executive cabin. Resale and maintenance considerations for this specific serial include engine-time tracking for the twin Honeywell TFE731-20 powerplants and adherence to avionics lifecycle updates for the Primus 1000/UNS-1Ew systems, factors that influence the documented valuation of $2,272,500.
