N403UP

This airframe, registered as N403UP, is a Boeing-built freighter originally manufactured in 1987 with constructor serial number 23725. The airframe is a converted passenger-to-freighter of model Boeing 757-24APF, operated and owned by United Parcel Service Co. based in Louisville, KY, US, and registered in the US. As a main-deck freighter it entered service following a purpose-driven conversion and has been employed within the UPS network; no other ownership transfers are recorded in the provided data. The aircraft is presented as an active fixed-wing multi-engine cargo platform with a forward cargo door and no passenger cabin.

The airframe features a main-deck freighter cabin layout following a P–F conversion with a forward cargo door and explicitly no passenger cabin, configured to carry palletized and containerized cargo rather than passengers. Operated by United Parcel Service Co. out of its Louisville, KY base, typical missions for this type include medium- to long-range overnight express and trunk routes across continent-scale networks up to the listed 3,150 nm range, flown at a cruise of roughly 458 kts to meet time-sensitive logistics schedules. Maintenance considerations for this specific installation center on freighter-unique structures such as main-deck cargo loading systems and reinforced floors; avionics fit and configuration details are not published in the supplied data.

The Boeing 757-24APF occupies a niche as a narrow-body, medium-range freighter with higher payload capability and longer range than typical regional freighters, powered in this example by twin Pratt & Whitney PW2040 engines producing 40,900 lbf each. In the aftermarket, converted 757 freighters are sought after by integrator and cargo operators for their combination of range, payload, and runway performance; competing models include larger freighter types for higher capacity and smaller converted narrowbodies for lower-cost regional missions. Resale and maintenance considerations hinge on airframe hours, structural condition after conversion, and the availability of certified spare parts for the PW2040 powerplants.
