N439UP

This airframe, registered as N439UP, is a Boeing-built freighter completed in 1994 with manufacturer serial number 25470. The airframe is a Boeing 757-24A(PF) and is owned by United Parcel Service Co of Louisville, KY, US, reflecting its dedicated role in parcel and cargo operations. Registration is under the US registry and the type has been operated in a main-deck cargo configuration with only minimal flight-crew seating, a configuration consistent with its corporate owner’s express freight network. Condition highlights are limited to the supplied data, which emphasize its freighter conversion and continued service for the corporate operator.

The cabin is configured as a freighter with main-deck cargo capacity and only minimal flight-crew seating, reflecting a mission profile centered on freight carriage rather than passenger transport. Typical operations for this airframe would be medium- to long-range cargo sectors within the operator’s network, exploiting a maximum range of 3,920 nm and a cruise speed of 458 kts to link regional hubs. Based at Louisville, KY, US under United Parcel Service Co ownership, the aircraft’s operational considerations prioritize cargo handling systems, structural integrity of the main-deck conversion, and engine support for the twin Rolls-Royce RB211-535E4 mounts. Avionics fit and specific onboard systems are not published in the supplied data.

The Boeing 757-24A(PF) airframe occupies a niche for narrow-body, medium-range freighter work, offering higher payload-range capability than many regional turboprops while retaining lower operating costs than widebodies on thin long-haul lanes. With twin Rolls-Royce RB211-535E4 engines producing 40,100 lbf each, the type competes with converted narrow-body freighters in the same segment. Buyer and operator demand typically favors established cargo carriers and integrators; maintenance and resale considerations for this specific airframe hinge on its freighter conversion state, engine time, and remaining structural life as indicated by its 1994 build serial 25470.
