N418UP

The airframe, registered as N418UP, is a Boeing-built freighter delivered in 1990 with manufacturer's serial number 23905. It is a converted production freighter variant of the 757 series, marketed as the Boeing 757-24APF, and has been operated in cargo service by owner UNITED PARCEL SERVICE CO based in Louisville, KY, US. The aircraft carries a US registration and its lifecycle includes conversion to a main-deck freighter (converted PF) to meet express cargo demands. Maintenance and valuation notes for this individual ship emphasize its role as a service-configured freighter in UPS's fleet rather than a passenger configuration.

The airframe operates in a freighter cabin layout with main-deck cargo capacity following its passenger-to-freighter conversion (PF); passenger fittings were removed and the cabin outfitted for palletized and containerized cargo. Typical mission profiles for N418UP include medium- to long-range express cargo routes within UPS's network, leveraging a cruise speed of 458 kts and a range of 3,920 nm to support transcontinental and regional high-frequency services from its Louisville hub. Avionics and systems are consistent with production 757 freighter standards, and maintenance cycles reflect the two-shift heavy-utilization pattern typical of major integrator operations. Unique operational considerations for this specific airframe center on main-deck cargo handling adaptations and the airframe's aging-series maintenance planning given its 1990 build year.

The Boeing 757-24APF occupies a niche as a medium-capacity, medium-range narrow-body freighter offering higher payload and range than typical narrowbodies while retaining efficient twin-engine economics via the Pratt & Whitney PW2040 powerplant. Competing types in the same market niche include reworked 737-300/400 freighters and converted A321 freighters, with demand driven by integrator fleets and express operators. Resale and maintenance considerations for this serial and age include continued inspection focus on structural fatigue items and lifecycle component pools, balanced against steady demand for 757 freighters in cargo conversion markets.
