N456UP

The airframe bearing tail number N456UP is a Boeing-built narrow-body freighter originally manufactured in 1996 under constructor serial 25477 and delivered as a passenger variant of the 757 family. It is recorded in corporate ownership by UNITED PARCEL SERVICE CO, based in Louisville, KY, US, and is operated in the operator's US domestic freighter fleet. The airframe was modified from its original passenger layout to a main-deck palletised freighter (PF) configuration, a registry and configuration change reflecting its transition into cargo service. Condition notes and formal valuation have not been published in the supplied data.

This specific 757-24A(PF) is configured as a main-deck freighter for palletised cargo; its cabin prior to modification featured 178 passenger seats as built. As a palletised freighter (PF) conversion, the main-deck interior is fitted for bulk and pallet loads with associated reinforced flooring, cargo handling gear and large cargo door installations typical of such conversions; these structural and systems changes drive unique inspection and maintenance cycles compared with passenger variants. Based in Louisville under UPS ownership, its typical mission profile centers on medium- to long-range domestic and transcontinental cargo routes within the operator’s network, exploiting the model’s payload and range balance. Avionics fit and detailed equipment lists for this airframe are not published in the supplied data.

The Boeing 757-24A(PF) sits in a niche between smaller narrow-bodies and larger widebody freighters, offering a payload-capable, transcontinental freighter with cruise speeds near 458 kts and a service ceiling of 42,000 ft. Competing models for similar missions include re-engined or converted narrow- and mid-size freighters; demand has been steady among integrators and express operators for converted 757s due to their efficient twin-engine performance and runway performance. Resale and maintenance considerations for this airframe emphasize life-limited components tied to its RB211-535E4 engines and the structural implications of its main-deck palletised conversion.
