N924UP

This airframe, registered as N924UP, is a Boeing-built Boeing 727-31C constructed in 1967 with manufacturer serial number 19234. The aircraft is registered in the United States and is owned by UNITED PARCEL SERVICE CO of Louisville, KY, US, reflecting a transition from passenger to cargo operations during its service life. The type has been operated from the owner's hub in Louisville and is noted in records as a freighter-converted former passenger 727, with its condition and valuation historically tied to its conversion state and remaining structural life. Conversion to freighter configuration and sustained operation under UPS are the most significant registry and role changes recorded for this airframe.

The aircraft’s cabin has undergone a freighter conversion from its earlier passenger layout, which had been configured for approximately 134 seats; the current fit prioritizes cargo handling and reinforced flooring consistent with freighter modifications. Avionics and mission systems are appropriate to legacy Boeing 727 conversions used in dedicated cargo service, supporting routine medium-haul feeder and express freight routes from the operator’s Louisville base. Typical operations center on time-sensitive parcel and cargo distribution across domestic networks, leveraging the aircraft’s range of 2,300 nm and high-altitude capability. Maintenance considerations specific to this airframe include management of three Rolls-Royce Tay powerplants and aging airframe systems common to late-1960s production 727s, with inspections and structural checks emphasized following conversion.

The Boeing 727-31C occupies a niche as a trijet freighter derivative of a late-1960s passenger jet, offering moderate range and payload capability for regional and transcontinental cargo missions. Competing models in the same era and mission set included converted narrowbodies and dedicated freighter derivatives from other manufacturers, with market demand driven by operators needing robust, older airframes for low-cost cargo carriage. Resale and maintenance considerations for this airframe are influenced by its 1967 build date, serial 19234, and the logistics of supporting Rolls-Royce Tay engines and legacy 727 systems in a modern cargo fleet.
