N605S

This entry covers airframe N605S, a 2008-built Bombardier CL-600-2B16 Challenger 605 with serial number 5788. The aircraft is owned by Sierra Aviation Inc, a corporation based in Kansas City, MO, US, and is registered in the US. The Challenger carries a published valuation of $10,188,878 and, as a 2008 model, presents as a mid-life example within its type certificate; registered in the United States is the primary notable registry action on record for this airframe. Operational condition and market valuation reflect its installed equipment set and standard corporate configuration.

This specific Challenger 605 is fitted internally in a typical 2-zone executive layout with 9–12 passenger executive seating while retaining certification for 22 seats, allowing flexibility between corporate transport and higher-density configurations. Avionics are provided by a Rockwell Collins Pro Line 21 suite, supporting contemporary flight-deck functionality for long-range business missions. Operated from Kansas City, MO, the aircraft’s performance—cruise of 459 kts and range of 4,123 nm—makes it suitable for transcontinental and transborder corporate missions under Sierra Aviation Inc. Maintenance considerations tied to this airframe include standard support for the GE CF34-3B engine family and system upkeep associated with Pro Line 21 avionics hardware typical of late-2000s Challenger 600-series installations.

As a Bombardier CL-600-2B16 Challenger 605 airframe, N605S sits in the market niche for midsize to super-midsize business jets offering long-range transcontinental capability, as evidenced by its 4,123 nm range and 41,000 ft ceiling. Buyer and charter demand for 2008 Challenger 605 examples is influenced by installed avionics, engine status, and cabin fit—elements present on this airframe (Pro Line 21 and GE CF34-3B engines)—which also drive maintenance cycles and resale pricing. The listed value of $10,188,878 reflects those configuration and age factors and informs considerations for operators balancing upgrade, overhaul, or replacement decisions.
