N553LM

This airframe, registered as N553LM, is a Bombardier Learjet 31A built in 2000 with serial number 31-193. The aircraft is owned by TURBINE AIRCRAFT SERVICES LLC, an LLC based in Bethany, OK, US, and is registered in the US; no earlier owners or transfers are published in the supplied data. Notable registry and condition highlights from the broker listing indicate a VIP/medical-capable interior and a market valuation of $1,395,000, reflecting its age, avionics upgrade set and single-operator status.

The Learjet 31A airframe is outfitted in a VIP/medical-capable configuration described in the broker listing as a forward club with 4 seats, a three-place aft divan, and a forward belted lav/“potty” seat that is electrically flushing for additional operational flexibility. Avionics fitment on this specific ship includes a Universal UNS-1Ew WAAS/LPV FMS, King EFIS-50 (5-tube) with KFC 3100 autopilot, ACSS MST-70B transponder (ADS‑B Out), TCAS II (Change 7), AlliedSignal Mark VII EGPWS/TAWS, and an L3 WX‑1000 Stormscope — equipment that supports RVSM-altitude operations and modern navigation procedures. Typical mission profiles for this airframe, given its range and cruise, include short- to medium-range corporate flights, medevac or on-demand charter sorties from its operator base in Bethany, Oklahoma. Maintenance considerations follow Learjet 31A norms, with attention to aging airframe systems and calendar-limited items given the 2000 build year.

The Learjet 31A occupies the light, high-speed end of the business jet market, notable for a high service ceiling (51,000 ft) and fast cruise (441 kts) for point-to-point missions. Competing models in the same niche include later-model light jets and early midsize used market types; buyers often seek upgraded avionics and well-documented maintenance to mitigate age-related resale risk. The listed value of $1,395,000 reflects factors common to the type: efficient short-haul performance, limited cabin volume compared with newer designs, and the importance of updated navigation/TCAS/TAWS packages for ongoing charter or medical operations.
