N28551

This airframe, registered as N28551, is a Boeing 747-48E(M) completed in 1997 with manufacturer serial number 28551. The airframe is owned by BANK OF UTAH TRUSTEE, a corporate trustee based in Salt Lake City, UT, US, and is recorded on the United States civil register (US). The aircraft’s configuration and registry indicate a combi main-deck capability and an upper-deck passenger cabin, and its documented status reflects trustee ownership rather than an active commercial operator. Recorded ownership under a corporate trustee suggests a financial or asset-management role in the aircraft’s lifecycle rather than day-to-day airline operation.

The specific cabin for this airframe is configured as a combi: main-deck cargo/passenger capability with an upper deck dedicated to passengers, enabling mixed cargo and high-density passenger operations on a single frame. Typical mission profiles for this configuration include long-range, high-capacity passenger services combined with palletized or containerized cargo carriage on the main deck, suited to transoceanic or high-density trunk routes within the aircraft’s 7,260 nm range and cruise at 504 kts. Maintenance considerations for this airframe would reflect the high-utilization combi layout and the four CF6-80C2B1F engines, each producing 62,100 lbf of thrust, requiring operator oversight for structural main-deck modifications and regulatory compliance for mixed cargo/passenger operations. The trustee ownership and lack of a named commercial operator in the record imply periods of storage, transition between operators, or use as a financial asset rather than continuous airline deployment.

The Boeing 747-48E(M) sits in the high-capacity, long-range widebody category, optimized for markets demanding large seat counts—this airframe’s 660-seat potential underscores that role. Competing models historically included other high-capacity variants of the 747 family and early high-density configurations of later twinjets; however, four-engine large-frame aircraft face different demand dynamics and maintenance costs compared with modern twin-engine long-range types. For trustee-owned examples like N28551, resale and leasing prospects hinge on demand for combi configurations and the airframe’s remaining structural and engine life, with maintenance-intensive attributes and regulatory approvals influencing marketability.
