N640SD

The airframe, registered as N640SD, is a 1994-built Learjet 60 with manufacturer designation Learjet Inc and serial number 60-040. This specific jet is on the U.S. registry and is owned by TRIGGER AIR LLC, an LLC based in Wilmington, DE, US; it is operated from that ownership address as the primary operator/home base. Registered in the United States under the current limited liability company owner, the airframe’s recorded market valuation stands at $1,400,000, reflecting its age, configuration, and residual market position. Maintenance status and detailed recent registry actions are limited to the recorded U.S. registration and ownership entry.

The aircraft’s eleven-seat configuration positions it for light to midsize corporate transport missions, typically supporting short- to transcontinental trips within the Learjet 60’s published range of 2,451 nm at a cruise of 453 kts. Cabin layout for this airframe is consistent with an eleven-seat executive interior, enabling multi-passenger corporate flights or light charter work; specific interior fit, galley, or entertainment equipment records are not supplied in the available data. Operated under TRIGGER AIR LLC from its Wilmington, DE address, the jet would commonly be scheduled for business point-to-point travel, air ambulance alternates, or air taxi missions depending on operator choice and regulatory approvals. Maintenance considerations for this airframe follow Learjet 60 norms tied to twin PW305A engines and aging 1994 airframes, with resale and serviceability influenced by total hours, avionics upgrades, and life-limited component status (not individually published).

The Learjet 60 occupies the light-medium business jet niche with high cruise speeds and a service ceiling of 51,000 ft, competing historically with aircraft such as the mid-size offerings from Dassault Falcon and Hawker/Beechcraft models. With twin PW305A engines producing 4,600 lbf each, the type is valued for climb performance and cruise efficiency for its class. Market demand for a 1994 airframe like N640SD is tempered by age, systems modernization needs, and a reported valuation of $1,400,000, making maintenance history and avionics retrofits primary determinants of resale prospects. Fixed-wing multi-engine operational costs and parts availability for older Learjet 60s remain key considerations for prospective buyers or charter operators.
