N789SR

This airframe, registered as N789SR, is a 1995-built Bombardier Learjet 31A with manufacturer serial 31-083 / 0083. It is owned and operated by North Slope Borough, a government entity based in Alaska, US, and has been offered with a documented valuation of $549,000. The airframe is listed in US civil registration and has been configured and advertised with specific avionics and a dedicated air‑ambulance interior, reflecting its role under municipal ownership. The combination of government ownership and an air‑ambulance layout is a notable operational configuration for this serial.

This specific Learjet 31A is fitted in a dedicated air‑ambulance layout featuring an aft two‑place divan and a forward‑facing stretcher/seat, while typical executive configurations for the type accommodate six passengers. Avionics advertised on the sale listing include a Bendix/King EFS-50 EFIS, dual UNS-1Ew FMS, KFC 3100 IFCS, TCAS II, and KGP 860 EGPWS, supporting precision navigation and safety systems for medical and short‑notice missions. Based with North Slope Borough in Alaska, mission profiles would logically prioritize medevac and urgent regional transport, operating from austere and remote facilities where aircraft performance and reliable avionics are critical. Maintenance considerations for this airframe include support for Honeywell TFE731-series engines and systems common to 1990s Learjet cockpits as presented.

The Bombardier Learjet 31A occupies a light, high‑speed business jet niche known for rapid climb and high cruise speeds, with a service ceiling of 51,000 ft and transregional range near 1,290 nm. Competing types in the era include other light jets with similar speed and mission capability; the 31A’s avionics and air‑ambulance conversion enhance its appeal to government and EMS operators. Market and resale considerations for this serial include age (1995 build), the dedicated medical interior which can limit buyer pool, and a listed market valuation of $549,000, factors that influence demand, refurbishment needs, and operational economics.
