N139LR

The aircraft bearing tail number N139LR is a 1997-built Learjet 31A, serial 31-139, manufactured by Bombardier Aerospace under the Learjet brand. The airframe is registered in the United States and is recorded as owned by the corporation Bank Of Utah Trustee, based in Salt Lake City, UT, US; this ownership is the principal known change in the aircraft’s custodial history. The asset is commonly cited in records with an estimated market value of $900,000, reflecting its age, configuration and typical maintenance status for a late-1990s light business jet.

The airframe for N139LR typically carries a six- to ten-place executive interior, with common configurations reported as club seating and either a divan or a belted lavatory seat variant; individual cabin furnishings may vary by retrofit. Avionics commonly fitted to this model include the King EFIS-50 suite coupled with a KFC-3100 autopilot installation, though specific fitment on this airframe may vary. Operated from its registered base in Salt Lake City, the aircraft’s performance envelope and cabin layout suit short- to mid-range corporate missions, air taxi and fractional operations, with the light-jet speed and ceiling supporting high-altitude, fast point-to-point trips. Maintenance considerations typical to this airframe class include aging-system refurbishment and periodic engine shop visits commensurate with TFE731 powerplant care.

The Learjet 31A occupies the late-1990s light business-jet niche, offering high cruise speeds and a very high service ceiling relative to many contemporaries, appealing to operators prioritizing speed and climb performance. Competing types in the market era include other light-cabin jets with similar mission profiles; resale and charter demand are influenced by interior condition, avionics currency and engine life-limited component status. For this specific airframe, the listed valuation of $900,000 positions it among mature-market examples where buyers factor modernization costs and the availability of parts and qualified maintenance for the Learjet lineage.
