N452SD

The airframe bearing registration N452SD is a Learjet 45 built in 2011 with serial number 45-428. The aircraft is recorded as owned by the corporation JET QUEST LLC, located in Hunting Valley, OH, US, and is entered on the US civil register. Its manufacturer is listed as Learjet Inc.; the current notable registry action is its registration to JET QUEST LLC, reflecting corporate ownership and operator stewardship based in Ohio. Condition and valuation specifics are not published in the supplied data, but the airframe’s relatively recent build year places it among later-production Learjet 45 examples.

The airframe is fitted with an executive flat-floor cabin configured in the typical Learjet 45 layout capable of 8–12 seats, and for this example is presented with a 12-seat arrangement under owner configuration flexibility. Avionics fit is a common Learjet 45 installation: Honeywell Primus-series equipment, supporting standard executive navigation, communication and flight-management functions for regional and transcontinental missions. Typical operations for this type include high-speed business transport and on-demand charter legs within the aircraft’s 1,700 nm range and at cruise speeds near 445 kts, operating from the owner/operator base in Hunting Valley, OH, US. Maintenance considerations reflect twin TFE731 turbofan logistics and the airframe’s certification and inspection cycles as a fixed-wing multi-engine corporate jet.

The Learjet 45 family occupies the light-to-mid-size business jet niche, prized for high cruise speed and a service ceiling to 51,000 ft that enables efficient point-to-point routing. Competing models in this segment include later-model light jets and older midsize designs that offer similar mission capability; buyer demand typically favors well-equipped, low-time examples with modern avionics such as the Honeywell Primus-series. Resale and maintenance considerations for this airframe center on engine maintenance of the Honeywell TFE731-20BR units, avionics supportability, and market preferences for executive flat-floor cabins and flexible owner-configurable seating.
