N438UP

This airframe, registered as N438UP, is a narrow-body freighter built in 1994 by Boeing Commercial Airplanes with manufacturer's serial number 25469. Operated and owned by UNITED PARCEL SERVICE CO (a corporation based in Louisville, KY, US), the aircraft carries the US civil registration US and is configured for cargo operations. The airframe is a factory-converted freighter variant designated Boeing 757-24APF and is catalogued as a fixed-wing multi-engine transport; its ownership history is characterized by long-term fleet assignment to a single corporate operator. Recorded as part of UPS’s dedicated freighter fleet, this airframe has been maintained to airline cargo standards throughout its operational life.

The configuration for this particular airframe reflects its freighter role as a Boeing 757-24APF, with cargo handling features and an internal layout optimized for unit-load device and palletized freight rather than passenger accommodations, although the type certificate supports a 178-seat passenger variant. Avionics and systems conform to the 757 family baseline as fitted at manufacture and as sustained through operator-specific maintenance programs. Typical mission profiles emphasize medium- to long-range cargo routes within the fleet’s operating network, leveraging a range of 3,915 nm and a cruise speed near 493 kts to support overnight and regional long-haul services from the operator’s Louisville, KY base. Maintenance considerations align with RB211 engine program requirements and freighter-specific structures and systems inspections.

The Boeing 757-24APF occupies a niche as a medium-capacity freighter derived from a popular narrow-body passenger airliner, offering high cruise speed and a service ceiling of 42,650 ft for efficient point-to-point cargo operations. Its primary competitors in the freighter conversion market include other narrow-body conversions offering similar payload-range tradeoffs; demand is driven by integrators and cargo carriers seeking reliable medium-range capability. Resale and maintenance considerations for this serial and year hinge on RB211 engine support, airframe hours, and the health of the freighter conversion market for 1990s-era 757s.
