N31LJ

The airframe bearing tail number N31LJ is a 1994-built Learjet 31A, constructor serial 31-097, manufactured by Learjet Inc. The aircraft is registered in the United States and is registered to DELTA NOVEMBER LLC, an entity based in Lewes, DE, US, which appears as the current listed owner and operator for this airframe. The airframe’s registry and ownership history reflect its operation as a small executive transport; its most recent valuation is $800,000, indicating a market position consistent with late-model light business jets in used condition.

This specific Learjet 31A is configured in a typical executive interior, a 6–8 place executive club layout with a forward refreshment/galley and a belted lavatory, reflecting the common fitted arrangements for the type. Avionics fit on this airframe is representative of many 31A examples, typically featuring a King/Bendix EFIS (EFIS-50) and a KFC-3100 autopilot, though individual retrofits and variations may apply. Operationally the airframe is optimized for short to medium international missions and high-speed point-to-point executive transport, offering rapid cruise and high-altitude capability from bases such as its home in Lewes, DE. Maintenance planning for this airframe follows standard light-jet programs for the TFE731 powerplants and Learjet airframe items; cabin amenities and the belted lavatory reflect a layout emphasizing compact executive comfort and mission flexibility.

The Learjet 31A family occupies the light, high-performance business jet niche, prized for high cruise speeds and a 51,000 ft service ceiling that enable efficient, fast routing. Competing models in the same market segment include other late-model light jets; demand is primarily from owner-operators and small charter operators. Resale and maintenance considerations for this airframe center on component life limits, avionics retrofit history, and the condition of the TFE731 engines, all factors that influence values around the listed $800,000 for a 1994 serial-31-097 example.
