N485MC

This entry documents airframe N485MC, a freighter conversion delivered in 2000 with manufacturer serial number 30607. The airframe is a converted passenger-to-freighter variant listed as Boeing 747-45EF/SCD, operated in trust ownership by UMB BANK TRUSTEE whose corporate registration is in Salt Lake City, Utah, United States. The airframe carries US registration (US) and is configured as a main-deck palletised freighter with a side cargo door, representing a late-model 747-400 series freighter platform with typical mid-life maintenance considerations tied to hull age and heavy freighter utilization.

The cabin is fitted as a main-deck palletised freighter with side cargo door (SCD), allowing large-unit cargo pallets and containers to be loaded on the main deck and facilitating express freight and long-haul cargo routes. With a published range of 7,260 nm and cruise speed near 492 kts, the aircraft is suited to intercontinental freight sectors, triangular transoceanic schedules, and high-utilization integrator services operating from the owner’s corporate location in Salt Lake City, UT. As a four-engine freighter powered by GE CF6-80C2B1F engines, routine heavy maintenance and life-limited component tracking are key operational considerations for this specific airframe given its 2000 build year and freighter mission profile.

The Boeing 747-45EF/SCD occupies a niche for high-capacity, long-range freighter operations where main-deck pallet capability is essential; its performance—ceiling 45,000 ft and range 7,260 nm—compares favorably to other large freighters in slot- and volume-constrained markets. Competitive alternatives include newer-generation twin-engine freighters for lower fuel burn, but four-engine 747 freighters retain demand for outsized and high-density cargo. For this airframe, resale and continued operation weigh heavily on maintenance history, remaining structural checks from the conversion, and ongoing engine shop visit cycles for the CF6-80C2B1F set.
