N521CH

The airframe bearing tail number N521CH is a Learjet 45 built as serial 2023 by Learjet Inc. The U.S.-registered airframe is owned by individual trustee SOLOMON MARK TRUSTEE, based in Wilmington, DE, US, and is recorded in U.S. civil registry records as having a 12-seat configuration. Registry documentation highlighting a 12-seat listing is a notable entry for this specific N-number relative to the model’s typical executive layouts. The aircraft’s market valuation is listed at $3,000,000, reflecting its age and configuration at time of record.

This airframe’s cabin is described consistent with the Learjet 45 family’s executive fit: a typical 8–9 place executive layout is common for the model, while registry entries for N521CH list 12 seats, indicating either a higher-density executive/airliner-style interior or a supplemental seating arrangement recorded for the specific aircraft. Avionics are reported in the fleet standard as the Honeywell Primus 1000, supporting typical high-speed, short- to mid-range business missions. Typical operations for this airframe profile include corporate and on-demand charter missions within the continental U.S., leveraging a cruise speed of 436 kts and a maximum operating ceiling of 51,000 ft; the owner’s base in Wilmington, DE, suggests frequent Northeastern corridor and transcontinental mission capability. Maintenance considerations follow Learjet 45 cycles and Honeywell TFE731-20 engine support requirements.

The Learjet 45 family occupies a light to light-medium business jet niche with a balance of speed, range and runway performance suitable for corporate operators and charter fleets. Competing models historically include light jets offering similar speed and range but differing cabin dimensions and operating economics. Buyer and charter demand for a post-2000 Learjet 45 will hinge on engine program status, avionics pedigree such as the Honeywell Primus 1000, interior configuration (notably the registry-listed 12 seats for N521CH) and overall valuation around $3,000,000, with resale and maintenance considerations driven by avionics upgrades and engine life remaining.
