Model & Market Context
This article covers the specific airframe N31LR, a 1998-built Learjet 31A serial number 150 manufactured by Learjet Inc. The aircraft is registered in the US and is owned by WORLDWIDE AIRCRAFT SERVICES INC of Tampa, FL, US, which is recorded as the operator/home base in listing materials. Registry records and broker listing materials identify a recent marketing valuation and condition summary putting the airframe at approximately $950,000, with listing notes describing an executive interior and avionics fit for continued business-jet use. A broker listing for this tail references an 8-passenger configuration with belted lavatory and two-place divan option, highlighting an interior layout variation from standard line configurations.
The cabin for N31LR is listed in broker materials as an executive arrangement suitable for business travel, noting a typical 6–8 place layout and the specific 8-passenger configuration with belted lavatory and two-place divan option associated with this airframe. The avionics fit identified for this airframe includes a Bendix/King EFIS flight deck as shown in listing documentation, with KFC-series autopilot typical for the model. Operationally, the airframe’s combination of a 1,290 nm range, 441 kt cruise and 51,000 ft ceiling supports short-to-medium haul executive missions from its base in Tampa, FL, consistent with charter, corporate repositioning, and owner-flown business use. Maintenance considerations in listing notes reflect the standard twin-TFE731 powerplant configuration and the avionics suite as key elements for continued serviceability and dispatch.
As a Learjet 31A airframe, N31LR sits within a light, high-performance fixed-wing multi-engine category produced by Learjet Inc. The aircraft’s performance figures—high cruise speed and high-altitude ceiling—define its operational niche for rapid point-to-point executive transport. Market and resale considerations for this specific serial include the airframe’s 1998 build year, the installed Bendix/King EFIS and typical KFC-series autopilot equipment, and the broker-referenced cabin options; these factors are reflected in the listed valuation of $950,000 and inform buyer and charter demand for this unit.
