N406UP

The airframe registered in the United States as N406UP is a Boeing 757-24APF built by The Boeing Company in 1988, bearing manufacturer serial number 23728. It is owned by United Parcel Service Co, a corporate owner based in Louisville, KY, US, and configured as a main-deck palletized freighter; the aircraft carries US registration and has operated in cargo service under UPS ownership. The combination of its 1988 build year and continued corporate ownership suggests a well-documented maintenance history consistent with airline-operated freighters of its vintage. Remaining in service with a major express freight operator places this airframe within an established logistics network centered on Louisville, its operator/home base.

N406UP is equipped in a freighter configuration with a main-deck palletized/cargo layout and no passenger cabin, reflecting its dedicated role for unit-load and palletized freight movements. Operated by United Parcel Service Co from its Louisville base, this airframe typically performs express cargo missions optimized for medium- to long-range trunk routes within North America and beyond, leveraging a 3,150 nm ferry/mission range and a cruise speed of 458 knots. The twin Pratt & Whitney PW2040 engines provide commonality with other 757 freighters, affecting maintenance scheduling and parts logistics; routine heavy checks would follow operator and manufacturer programs for a late-1980s airframe in continuous commercial service.

The Boeing 757-24APF occupies a niche as a narrow-body, medium-range freighter that balances payload and range for express freight carriers. With a cruise speed of 458 knots and service ceiling to 42,000 feet, the type competes functionally with converted narrow-body freighters and newer medium freighters in intra-continental networks. For buyers and lessors, considerations for an airframe like N406UP include lifecycle maintenance of PW2040 engines, airframe fatigue and corrosion inspections typical of a 1988 build, and the desirability of a palletized main-deck layout for express carriers prioritizing unitized cargo throughput.
