N240B

The airframe bearing tail number N240B is a Learjet 31A built in 1999, carrying construction serial number 175. The documented owner is the corporation THUNDERUN AVIATION CORP, based in Glenwood, NY, US, and the aircraft is registered in the US. Registered in the United States under corporate ownership, this specific airframe is valued at $986,000, a figure that reflects its late-1990s manufacture, equipment fit and current registry status.

The cabin is noted as a typical executive 6–8 place layout in practice, with the registry listing 10 seats, and the interior fit in this airframe includes club seating and an optional belted lavatory. Avionics for this Learjet 31A are the AlliedSignal / Honeywell EFIS-era digital suite specific to the 31A configuration, supporting the airframe’s high-altitude, high-speed mission profile. Operated from Glenwood, NY, US by THUNDERUN AVIATION CORP, the aircraft’s performance — a cruise of 441 kts and a service ceiling of 51,000 ft — suits short-to-medium stage executive transport and charter missions within its 1,290 nm range. Maintenance considerations for this airframe will reflect the twin TFE731-2B engines and the EFIS-era avionics fit, factors that influence inspection cycles, component overhaul intervals and potential avionics upgrades.

This airframe’s combination of a high cruise speed (441 kts), a high service ceiling (51,000 ft) and a relatively compact cabin (registry 10 seats, typical executive 6–8) defines its operational niche as a light, high-performance executive transport. The twin TFE731-2B engines and the aircraft’s delivered range (1,290 nm) frame typical mission capabilities and maintenance planning for owner-operators and corporate fleets. The listed value of $986,000 for this specific, 1999-built serial 175 emphasizes resale and life-cycle considerations tied to age, equipment standard (EFIS-era avionics) and documented seating/cabin configurations.
