N404UP

This airframe, registered as N404UP, is a Boeing 757-24APF built in 1987 with manufacturer serial number 23726. It is owned by United Parcel Service Co., a corporation based in Louisville, KY, US, and operated in a freighter role with a United States registration. The airframe was delivered new from The Boeing Company and has been operated as a main‑deck cargo aircraft; notable registry actions are limited to the established corporate ownership by United Parcel Service Co.. Condition and valuation remarks for this specific tail are not published beyond its role as an active freighter.

The airframe is configured as a main‑deck freighter with capacity for cargo pallets and containers and contains no passenger seating, reflecting a pure freighter conversion/production role for express and freight operations. Specific avionics fit and interior outfitting details for this serial are not published; operationally, such 757 freighters typically support medium- to long‑haul overnight and day‑turn routes within continental and transcontinental networks consistent with a 3,900 nm range and a cruise of 458 kts. Based out of Louisville, KY under the ownership of United Parcel Service Co., the aircraft’s mission profile emphasizes scheduled cargo feeder and long‑haul express services; maintenance considerations focus on main‑deck cargo handling systems and the two PW2040 engine type common to this conversion-class airframe.

The Boeing 757-24APF airframe occupies a niche as a medium‑capacity, narrow‑body freighter offering transcontinental range and higher cruise speed compared with typical narrow‑body freighters, driven by its 2 × Pratt & Whitney PW2040 engines and high‑altitude capability to 42,000 ft. Competing models in the freighter space include other converted narrow‑body types; demand from integrators and cargo operators remains strong for airframes that combine palletized main‑deck capacity with efficient cruise performance. Maintenance and resale considerations for this airframe emphasize the health and support of the PW2040 powerplants and the freighter‑specific structural and cargo handling modifications inherent to the 757 freighter configuration.
