N546DH

The airframe bearing registration N546DH is a 2005-built Bombardier Challenger 604 (CL-600-2B16), serial number 5606, manufactured by Bombardier Inc.. The aircraft is registered in the US and is owned by RDH AIR LLC (an LLC based in Omaha, NE, US). Acquisition by RDH AIR LLC represents the primary documented ownership; no other registry changes are published. Current market valuation for this specific airframe is listed at $5,000,000, reflecting age, configuration and typical Challenger 604 depreciation curves.

The fitted cabin for this airframe follows a typical executive layout configured for 10–12 passengers with common double-club seating, a forward galley and an aft lavatory; the model is certified to carry up to 19 passengers depending on configuration. Avionics are commonly the factory-fit Rockwell Collins Pro Line 4, though many Challenger 604 airframes, including examples of this series, have been retrofitted with optional upgrades to Pro Line 21 or later suites. Operationally, this Challenger 604 is suited to transcontinental and long-range business missions consistent with its 3,756 nm range and 459 kt cruise, typically operated from the owner-operator base in Omaha, NE, US. Maintenance considerations mirror the CF34 series engine support structure and legacy Challenger airframe programs.

The Bombardier Challenger 604 (CL-600-2B16) occupies the large-cabin, long-range business jet niche, offering transcontinental capability and a high, comfortable cabin environment with a service ceiling of 41,000 ft. Competing models occupy similar mission profiles; resale demand depends on avionics fit, interior condition, and engine cycle status. For a 2005 serial 5606 example valued at $5,000,000, buyers will weigh potential avionics upgrades (Pro Line 21 or later), interior refurbishments for wear, and ongoing CF34 maintenance track records when assessing lifecycle and resale considerations.
