The specific build year and early ownership history are not published, but current title records list the owner as the corporate entity 4D Aviation Ltd.

The cabin for this specific Learjet 35A is fitted in a typical executive configuration accommodating 6–8 passengers in club and divan seating arrangements common to the model. Specific avionics fit and line-item equipment lists for N610LJ are not published in the available data; therefore, standard mission profiles are inferred from the model’s executive layout. Typical operations for this airframe would center on short- to medium-range executive transport missions consistent with its 1,930 nm range and high-speed cruise of 436 kts, with utilization likely focused on business charter or corporate transport under the record of corporate ownership by 4D Aviation Ltd. Routine maintenance considerations follow established type practices for the Garrett/Honeywell TFE731 family.

The Learjet 35A occupies a long-standing niche as a light, high-performance business jet offering high cruise speeds and an operational ceiling of 45,000 ft, making it competitive for rapid point-to-point missions. Competing models in the light business-jet category offer similar speed and range trade-offs; market demand for older Learjet 35A airframes is influenced by maintenance status, engine times on the TFE731 series, and interior refurbishment. Resale and operational economics for this airframe are summarized by its recorded valuation of $960,000 and corporate ownership structure under 4D Aviation Ltd.
