N821AU

This airframe, registered as N821AU, is a Boeing 737-500 built in 1991 with manufacturer serial number 24821. The aircraft is registered in the United States and is owned by BANK OF UTAH TRUSTEE, a corporate trustee based in Salt Lake City, UT, US. Operator details and long-term home base are operator-specific and are not published in the available data; registry entries indicate standard US registration status without further noted transfer events. Condition and valuation highlights are not published beyond historical configuration notes indicating high-density single-class fittings during its operator service life.

The cabin configuration for this specific Boeing 737-500 is operator-specific; historically the type — and this airframe in particular — has been fitted in single-class high-density layouts accommodating up to 149 passengers. Avionics fit and interior amenities for N821AU are not published here and would vary by operator refit; historically such airframes supported regional to short transcontinental missions consistent with the model’s range and cruise performance. Typical mission profiles for this airframe would include high-frequency short- to medium-haul services where high-density seating and turnaround efficiency are prioritized. Maintenance considerations for this airframe follow the standard 737-500 legacy program, with attention to aging-aircraft inspections, CFM56-3 engine support, and configuration-specific interior lifecycle items.

The Boeing 737-500 occupies the small end of the Next-Generation/Classic 737 family niche, offering a balance of short- to medium-range capability and high-density seating for up to 149 passengers. Competing models in the same operational niche historically included regional narrowbodies and early-generation single-aisles; buyer and charter demand for classic 737-500s has been driven by availability, acquisition cost, and mission fit rather than new-technology efficiency. Maintenance and resale considerations for this serial-numbered airframe center on the legacy support environment for CFM56-3 engines, airframe hours and cycles, and the market appetite for high-density-configured, US-registered 737 classics.
