N500MP

The airframe, N500MP, is a Learjet 31A built in 2000 with serial number 31-198. It is registered in the United States and is owned by N500MP LLC, an Alma, Michigan–based limited liability company; the airframe appears in the register under that ownership. The current valuation for this specific aircraft is listed at $986,000, reflecting its age and equipment set. Maintenance and operational baselines reflect common upgrades for the model, and the owner/operator is based in Alma, MI.

The cabin of N500MP is fitted in a typical layout for the model: a six-place executive club arrangement forward, complemented by a forward belted lavatory and a small divan, though final cabin specifics can vary by interior refit. Typical avionics fits for this airframe reflect AlliedSignal/Honeywell EFIS installations, with KFC-3100 autopilot systems commonly retrofitted; this configuration supports precision IFR work and higher-altitude cruise. Operating from its Alma, MI base, missions for this airframe commonly include short to medium-range executive transport within the Learjet 31A’s 1,290 nm radius, high-speed trips at approximately 441 knots true airspeed, and flights taking advantage of its FL510 ceiling. Routine maintenance considerations mirror those of other late-model Learjet 31As, particularly attention to engine TFE731 lifecycle and avionics retrofit compatibility.

The Learjet 31A occupies the light, high-performance business jet niche within the fixed-wing multi-engine category, valued for high cruise speeds and a 51,000 ft service ceiling. Competing models typically include other light jets offering similar speed-range tradeoffs; buyer interest for older airframes like this often centers on value-conscious operators seeking high-performance, short-trip capability. Resale and maintenance considerations for this airframe reflect its 2000 build year, engine TBO economics, avionics retrofit paths (notably the KFC-3100), and the sub-million-dollar market valuation indicated.
