N90

This airframe, registered as N90, is a 2009-built Bombardier CL-600-2B16 Challenger 605 with manufacturer serial number 5817. It is owned and operated by the FEDERAL AVIATION ADMINISTRATION, based in Oklahoma City, OK, US, and is maintained in a configuration dedicated to FAA flight inspection and navigation-calibration duties. The airframe retains its US registration and a 22-seat certification while being modified to carry specialized inspection systems; its transition into FAA FlightCheck service represents its primary operational role rather than conventional charter or corporate transport. Condition and valuation particulars beyond configuration and role are not published in the provided data.

The aircraft is configured specifically for FAA flight inspection and calibration missions and certified to a 22-seat layout, while retaining the Challenger family’s two-zone cabin arrangement when used for transport. Avionics are centered on the Rockwell Collins Pro Line 21 integrated suite augmented with dedicated flight-inspection and navigation-calibration equipment for FAA FlightCheck missions. Typical mission profiles emphasize long-range, high-speed transits to calibration targets and on-station flight inspection work within the aircraft’s published range of 4,045 nm and cruise of 488 kts, operating from its FAA base in Oklahoma City, OK, US. Maintenance considerations focus on avionics calibration, mission-system support, and adherence to government flight-inspection standards rather than purely commercial passenger outfitting.

The Bombardier CL-600-2B16 Challenger 605 occupies the super-midsize business jet niche, offering long-range capability and a two-zone cabin popular for executive transport and specialized missions. Its performance—represented here by a 41,000 ft ceiling, 488 kt cruise, and 4,045 nm range—competes with contemporaries in the super-midsize class, where buyers include corporate operators, charter companies, and government agencies requiring missionized platforms. For this specific airframe, market and resale considerations are driven by its FAA mission equipment and government ownership, which can limit direct comparability to standard civilian-configured Challenger 605 examples and affect demand in secondary markets.
