N431DA

The airframe bearing tail number N431DA is a 1998-built Learjet 31A with serial 31-163, manufactured by Learjet Inc.. The airframe is recorded as owned by CHUCK INVESTMENTS LLC, headquartered in Franklin Furnace, OH, US, an ownership entry that defines its operator/home base as Franklin Furnace for registry purposes. Registry records and valuation assessments list the aircraft with a market value of $986,000, reflecting age, configuration and typical market depreciation for late-model light business jets. There are no publicly listed notable incident entries in the provided data; maintenance and retrofit activity is indicated by common airframe-specific avionics and autopilot upgrades rather than factory-original equipment.

The cabin for this specific Learjet 31A is noted as a typical executive 6–8 place club layout, while registry data lists 10 seats and indicates that some seats may be belted lavatory or divan positions, a configuration detail that affects passenger counts and utility. Typical avionics fits for this airframe type include Bendix/King EFIS-50 or equivalent EFIS coupled with a KFC-3100 autopilot; such airframe-specific retrofits are common and consistent with the equipment levels listed for this unit. Operationally the aircraft’s 1,290 nm range and 441 kt cruise speed suit short to mid-range executive missions, owner-operated flights, and ad hoc charter roles from its Ohio base. Maintenance considerations for this airframe emphasize engine hot-section inspections and avionics retrofit compatibility given the age and aftermarket upgrades typical to the model.

The Learjet 31A occupies the high-performance light business jet niche with a 51,000 ft ceiling and relatively fast cruise for its class, appealing to buyers needing speed and altitude capability in a compact platform. Competing models in the late-1990s light jet market included small-cabin jets from Cessna and Hawker, with purchaser decisions often guided by range, runway performance, and retrofit costs. Resale and maintenance considerations for this airframe reflect its 1998 build date and the prevalence of airframe-specific avionics and autopilot retrofits; such factors influence valuation, which is listed here at $986,000. Demand among owner-operators and niche charter operators tends to favor well-maintained examples with updated avionics and clear registry histories.
