N451SD

This article concerns airframe N451SD, a Learjet 45 built in 2010 with manufacturer's serial number 411 by LEARJET INC. The airframe is registered in the United States and is owned by FORTUNE AVIATION LLC, an LLC based in Longview, TX, US, which serves as the operator and home base for this specific airframe. Registered under U.S. civil registry and recorded with a market valuation of $3,000,000, the aircraft’s public record centers on its corporate ownership and typical executive configuration rather than any high-profile incidents or registry actions.

The cabin of N451SD is fitted with a forward galley and an aft belted lavatory and typically configured in an 8–12 passenger executive double-club layout on a flat-floor cabin, with the specific installation capable of accommodating up to 12 seats. Avionics are fitted with a Honeywell Primus 1000 suite in typical Learjet 45 installations, supporting the aircraft’s high-speed, mid-range executive mission profile. Operated from Longview, Texas by FORTUNE AVIATION LLC, the aircraft is optimized for point-to-point business travel within its published 1,971 nm range and cruise speeds near 436 knots, commonly used for regional and transcontinental hops consistent with charter or corporate flight departments. Maintenance considerations follow Learjet 45 practice items, with the twin Honeywell TFE731-20BR engines providing balanced performance for sustained cruise to the aircraft’s 51,000 ft service ceiling.

The Learjet 45 occupies the light-midsize business jet niche, offering higher cruise speeds and altitudes compared with earlier light jets while keeping operating costs competitive against larger midsize types. Typical competitors include other light-to-midsize executive jets that emphasize speed and altitude capability. Buyer and charter demand for a 2010 Learjet 45 like N451SD centers on operators valuing fast point-to-point performance and a flat-floor executive cabin; resale and maintenance considerations reflect age, engine TBO status, avionics configuration like the Honeywell Primus 1000, and the listed market valuation of $3,000,000.
