N425UP

This airframe, registered as N425UP, is a Boeing-built freighter completed in 1991 with manufacturer's serial number 25370. It is a Boeing 757-24APF converted to a main-deck cargo configuration and is owned by UNITED PARCEL SERVICE CO (a corporation based in Louisville, KY, US). The aircraft is registered in the United States and operated from the owner's Louisville base for package freighter missions. Valuation and condition details are Not published for this specific airframe.

The cabin layout for this airframe is a main-deck cargo configuration (package freighter) with the flight deck accommodating 2 crew seats; there is no passenger cabin. Avionics fit is consistent with conversion freight standards for the 757 freighter program (specific fitment not published for this serial). Typical mission profiles for N425UP include medium- to long-range fed-package operations using the aircraft’s approximately 3,900 nm range and cruise speed near 458 kts, operating primarily from the owner’s Louisville, KY base. Maintenance considerations reflect typical freighter usage—frequent flight cycles and cargo loading stress—aligned with UPS’s centralized heavy maintenance practices (detailed records for this airframe are not published).

The Boeing 757-24APF occupies a niche as a medium-capacity, narrow-body freighter with transcontinental and transoceanic range for its class, benefitting from the type’s higher cruise speed and efficiency compared with older narrow-body freighters. Competing models include derivative freighter conversions of other narrow-bodies in similar payload/range brackets; demand in the cargo market favors well-maintained 757 freighters due to their payload-range balance. Resale and maintenance considerations for this airframe hinge on engine life cycles of the Rolls-Royce RB211-535E4 pair and structural fatigue related to repeated cargo operations.
