N926UP

This entry covers airframe N926UP, a Boeing 727-31C delivered in 1967 with manufacturer serial number 19233. The airframe is registered in the US and has been owned by UNITED PARCEL SERVICE CO (a corporation based in Louisville, KY, US), reflecting its role in cargo operations. The 727-31C configuration and registration reflect a lifecycle oriented toward freight service, including a conversion to freighter / convertible freighter configuration that defined its later operational use. As a fixed-wing, multi-engine airframe, its corporate ownership and Louisville base tie it directly to integrated parcel and logistics operations.

This specific airframe carried a cabin layout consistent with a converted freighter / convertible freighter history, meaning original passenger fittings were removed or made removable to accommodate cargo pallets and bulk freight. Avionics and specific fitment details are not published for this tail number, but its operator-centric mission profile was freight haulage from the owner’s Louisville base, supporting regional and national logistics flows. Maintenance considerations for this aircraft would have included three-engine support and type-specific structural inspections associated with conversion work and continued high-utilization cargo service.

The Boeing 727-31C occupies a niche as a tri-jet regional to medium-haul workhorse of its era, appealing to cargo operators for its rear airstair, robust structure, and adaptability to freighter conversion. Competing models historically included earlier-generation narrowbodies adapted for freight, though the 727’s three-engine layout and conversion options made it particularly desirable for operators converting passenger frames. For buyers and lessors, maintenance and resale considerations hinge on airframe age (this unit dating to 1967), parts availability for the TAY turbofans, and the economic viability of continued operation in a cargo role by its corporate owner.
