N669MD

This entry documents airframe N669MD, a Learjet 31A built in 1992 with serial number 31-068. The aircraft is recorded as owned by registered to DMC AVIATION LLC, a corporation based in Scottsdale, AZ, US, and maintained in US civil registry. The airframe’s condition and market placement are reflected in an assessed value of $700,000, with standard executive outfitting and operational history consistent with light business jet usage. No further historic changes in ownership or notable incident records are published in the supplied data.

The airframe carries a typical executive interior layout, generally configured with 6–8 club seating typical though this registration is specifically listed with 10 seats, indicating a higher-density executive or corporate shuttle arrangement. Avionics aboard reflect typical Learjet 31A fits: Bendix/King EFIS from the EFS-50 family and many 31A airframes employ the KFC-3100 autopilot, with the caveat that individual fit varies by aircraft. Operationally the aircraft’s combination of a 1,631 nm range and 441 kt cruise speed positions it for short- to medium-range corporate missions, point-to-point charters, and owner-flown trips from its Scottsdale, AZ base. Maintenance considerations follow from its early-1990s vintage and the TFE731 series powerplant family, which influence parts, inspections and overhaul cycles.

The Learjet 31A sits in the light business jet niche, offering high cruise speeds and high-altitude capability (ceiling 51,000 ft) attractive for time-sensitive corporate missions. Competing models in this performance bracket typically include other small-cabin, high-speed jets; buyer demand often focuses on speed, runway performance and total ownership cost. For a 1992 airframe such as 31-068, resale and operational economics are influenced by avionics fit, interior configuration (here a 10-seat layout), and the TFE731 engine maintenance status, all factors that bear on marketability and cost of continued operation.
