N515CS

This airframe, registered as N515CS, is a 1999-built Learjet 31A bearing serial number 185. It is registered in the US and listed as owned by ABOVE THE CLOUDS LLC, a corporation based in Auburn, AL, US. The aircraft’s registry and ownership reflect a corporate operator profile based in Auburn; no other public registry actions or transfers are provided in the supplied data. Condition and valuation details are not published in the provided dataset.

The cabin is described as an operator-configured executive interior; a broker listing shows an eight-passenger executive layout with a mid-cabin four-place club and an aft forward-facing divan, plus forward belted crew seating, and notes the operator-configurable capacity up to 10. Avionics equipment listed for this specific airframe on the broker listing includes Bendix/King EFS-50 EFIS, Bendix-King KFC-3100 autopilot (IFCS), Universal UNS-1Ew FMS/WaAS LPV, and TCAS-II CAS-67A, supporting modern GPS approaches and traffic awareness. Typical missions for this airframe profile include regional business travel and on-demand charter flights within the aircraft’s roughly 1,266 nm range at cruise speeds near 450 knots, operating from the owner/operator’s Auburn, Alabama base. Maintenance considerations for this airframe would center on lifecycle and overhaul schedules for the twin Honeywell/AlliedSignal TFE731 powerplants and avionics integration tied to the listed EFIS/autopilot/FMS suite.

The Learjet 31A occupies the light, high-performance business jet niche, notable for high cruise speeds and a service ceiling up to 51,000 ft, making it attractive for operators seeking short-to-medium regional missions with fast point-to-point capability. With seating configurable for up to 10, it competes in the market with other light business jets for charter and corporate transport. Buyers and broker-market participants typically evaluate 31A airframes on engine TSOs, avionics upgrades (such as WAAS/LPV-capable FMS and TCAS), and airframe maintenance history; those factors strongly influence resale and charter appeal for late-1990s vintage examples like N515CS.
