N800CK

This airframe, registered as N800CK, is a 1998-built Learjet 31A with manufacturer serial number 157. The aircraft is recorded as owned by NATIONAL AEROTRUST SERVICES INC TRUSTEE (a corporate trustee located in Lewes, DE, US) and retains United States registration. The jet’s entry in civil records and trustee ownership indicate corporate asset status rather than active operator branding; valuation notes place the airframe at approximately $986,000, reflecting age and configuration. No separate operator name or multiple registration events are published beyond the trustee ownership in the supplied data.

The cabin of this specific Learjet 31A is fitted in an eight-passenger executive layout: forward belted lav, 4-place club mid-cabin, and a 3-place divan aft, yielding a nominal ten-seat certification with executive seating for eight. Avionics equipage includes a Universal UNS-1C FMS, Bendix/King KDC-481 nav/comm components, KAH-460 autopilot elements, AlliedSignal/Honeywell EGPWS, and TCAS II (Bendix CAS 67), supporting typical single-pilot or two-crew IFR business-jet operations. With a 1,290 nm mission range and a high-speed cruise near 441 kt, the airframe is configured for short- to mid-range corporate shuttle missions, air-taxi legs, and transregional hops from a U.S. home base. Maintenance considerations for this specific jet track typical Learjet 31A needs, including TFE731 series engine care and avionics support for legacy Bendix/King/Learjet systems.

The Learjet 31A family occupies the light, high-performance business-jet niche, prized for high cruise speeds and high-altitude capability (service ceiling up to 51,000 ft) relative to size. Competitors in the era and market include midsize and light-cabin types offering varying cabin comfort versus speed trade-offs; buyers often weigh the 31A’s speed and climb performance against newer-model cabin and systems amenities. Resale and maintenance considerations for a 1998 airframe like N800CK typically focus on completion condition, engine cycles on TFE731-2-3B powerplants, and avionics retrofits; the indicated value of $986,000 reflects these lifecycle and market factors.
