N818SB

The airframe bearing tail number N818SB is a 2007-built Bombardier Challenger 300 (BD-100-1A10), serial 20184, manufactured by Bombardier Inc. The aircraft is owned by SHADOW AIR LLC, an LLC based in East Chicago, IN, US, and carries a United States registration. No other recorded changes of ownership or notable registry actions are published in the supplied data. The airframe’s age (built in 2007) and factory-certified systems such as the Rockwell Collins avionics suite inform typical condition and valuation assessments for operators and appraisers.

The cabin for this model is described as a typical executive eight-passenger layout with forward and aft club seating, a forward galley, and an aft belted lavatory; the specific fit for N818SB is not published. Avionics are listed as Rockwell Collins Pro Line 21, with note that Pro Line 21 Advanced configurations are common on retrofits, indicating potential modernization paths for the installed avionics. Operated from an owner base in East Chicago, IN, US, the aircraft’s 3,100 nm range and 459-knot cruise speed suit medium- to long-range corporate missions and charter operations. Maintenance planning for this airframe would focus on twin Honeywell AS907-1-1A engines and age-related airframe/avionics inspection items typical of a 2007-built Challenger 300.

The Bombardier Challenger 300 (BD-100-1A10) occupies a performance niche defined by transcontinental range, high cruise speed, and a pressurized eight-passenger executive cabin as exemplified by N818SB’s specifications. Its twin Honeywell AS907 engines and Pro Line 21 avionics contribute to predictable operating costs and upgrade potential. Age (2007 build year) and installed equipment levels—particularly avionics retrofit options—are key considerations for buyers and charter operators assessing maintenance burden and resale value for this Challenger 300 airframe.
