Model & Market Context
The airframe registered as N31DT is a 1997-built Learjet 31A, serial number 31-147, manufactured by Learjet Inc. / Bombardier Aerospace. The airframe is owned by FA31DT LLC, a corporate owner based in Owasso, OK, US, and is operated from that home base for corporate and charter missions. The aircraft's registration is listed as US and the registry allows varying seating configurations up to ten seats; the operator typically registers the airframe in a corporate LLC rather than as an individual owner. There are no public records of major ownership transfers beyond the current corporate owner in the supplied data.
The cabin of this specific airframe is described as a typical executive layout with a 6–8 place executive club arrangement, though the registry lists up to 10 seats depending on outfitting, so configurations may be altered to match operator mission needs. Avionics in many Learjet 31A airframes follow a common fit: Bendix/King EFIS-50 displays with dual KFC-3100 autopilot; this airframe may also carry Universal/UNS‑1 FMS equipment depending on retrofit history, but the exact installed suite varies by retrofit. Typical mission profiles for the type and this operator include short- to mid-range corporate shuttle and on-demand charter trips within the aircraft’s approximately 1,631 nm range, operating efficiently at cruise speeds near 441 kts and leveraging a high-altitude capability up to 51,000 ft. Maintenance considerations for this airframe follow the Learjet 31A pattern, including attention to twin TFE731 series engine overhauls and avionics retrofit compatibility when upgrading EFIS and FMS systems.
The Learjet 31A occupies a light, high-performance business jet niche noted for high cruise speed and a high operating ceiling, exemplified by this airframe’s 441 kts cruise and 51,000 ft ceiling. Competing models in the segment include other late‑1990s light jets offering similar short-field capability and speed; resale and charter demand typically favor airframes with upgraded avionics and well‑documented maintenance. Owners and buyers of Learjet 31A airframes pay particular attention to TFE731 engine time, avionics retrofits (EFIS/FMS), interior condition and the flexibility of seat configurations when assessing maintenance and resale value.
