N620S

The airframe bearing tail number N620S is a Canadair-built business jet, a Canadair CL-600 Challenger (CL-600-1A11), completed in 1981 with serial number 1031. The documented legal owner is VALIAIR LC TRUSTEE, an LLC located in Ogden, UT, US, and the aircraft carries a United States registration. Current ownership is recorded under the Ogden-based trust/LLC, with no further operator or charter employment history published in the supplied data. Registry status is United States, and there are no published independent valuation or condition notes included in the provided dataset.

This specific CL-600-1A11 is configured in a 13-seat layout, reflecting a typical corporate transport cabin capacity for the Challenger series. The aircraft’s avionics package is recorded as the typical original fit of Sperry SPZ-600 / Collins Pro Line 1, which indicates legacy integrated flight and navigation systems consistent with early 1980s Challenger deliveries. With a cruise speed of 442 kt and a published range of 2,909 nm, typical mission profiles for this airframe would align with medium-haul corporate or charter trips within continental U.S. and transcontinental sectors. Based in the ownership location of Ogden, UT, maintenance considerations would follow standard Challenger practices for airframes and ALF-502 turbofan engines, noting that avionics and engine types are period-specific to this model year and may affect upgrade or refurbishment planning.

The Canadair CL-600 Challenger (CL-600-1A11) sits in the early Challenger family, designed to serve the medium-range corporate transport niche with twin ALF-502 turbofans producing 7,500 lbf thrust each. Competing models in its era offered similar cabin counts and range, and buyer or charter demand for this airframe is influenced by age, legacy avionics such as Sperry SPZ-600 / Collins Pro Line 1, and the need for potential avionics or propulsion updates. Maintenance and resale considerations for this exact airframe center on its 1981 build year, serial 1031, the ALF-502 engine support status, and any modernization of navigation and communication suites required to meet contemporary domestic operational standards.
