Model & Market Context
This airframe, registered as N36SP, is a 1985-built Learjet 35A (C-21A) with manufacturer serial number 35-577. The airframe is owned and operated by the government agency Kentucky State Police, based in Frankfort, KY, US, and carries United States registration. Acquisition by Kentucky State Police represents the primary recorded change of custody for this specific serial, and the aircraft is commonly described in registry listings with a market valuation of $1,000,000. Condition highlights and service history beyond basic registry entries are not published in the supplied data.
The airframe is configured with a two‑crew flightdeck and an executive cabin typically fitted for 6–10 passengers in a club/sofa layout; a state transport configuration is a documented alternate role for this installation. Routine operations for this aircraft under its current government operator would be consistent with short-to-medium‑range transport and missions that leverage the Learjet 35A’s transcontinental range of 2,100 nm and high‑cruise speed of 461 kts, operating from the Kentucky State Police home base in Frankfort. Specific avionics fit, bespoke communications suites, and detailed interior appointments for this airframe are not published in the provided data. Maintenance considerations reflect a twin‑engine, turbofan business jet type with Honeywell TFE731-series engines; lifecycle items such as engine program enrollment or specific airframe maintenance records are not supplied.
The Learjet 35A (C-21A) occupies a niche as a light, high‑speed, long‑range business/military transport platform well suited to government and VIP shuttle roles. Competing models in this performance band include other light jets offering similar cruise speeds and altitudes; buyer and charter demand for older 1980s airframes tends to emphasize maintenance history, avionics modernization, and engine program status. For this specific airframe, the listed valuation of $1,000,000 and its government ownership are key factors influencing resale prospects and operational deployment.
