N747SF

This airframe, registered as N747SF, is a conversion freighter built in 1979 with manufacturer's serial number 21575. It was produced by Boeing Commercial Airplanes as a Boeing 747-283B(SF) and is recorded in ownership under Aerospace Trust Management LLC Trustee of Wilmington, DE, US. The aircraft carries a United States registration and has been configured in a post-conversion freighter layout; notable registry actions are limited to its trustee ownership and U.S. registration. Condition and valuation details have not been publicly detailed beyond its converted main-deck palletized cargo capability.

The cabin of N747SF has been converted to a freighter with a main-deck palletized cargo configuration following its passenger-to-freighter modification; seating is listed at 495 in the original configuration but the operational layout is focused on palletized cargo throughput. Typical mission profiles for this airframe center on long-range, high-capacity cargo sectors enabled by a 6,218 nm range and a cruise speed near 517 kts, operating within the fixed-wing multi-engine category. Avionics fit and operator base are not published in the provided data; maintenance considerations primarily reflect heavy-airframe and JT9D engine support requirements inherent to late-1970s 747-class conversions and trustee-managed ownership arrangements.

The Boeing 747-283B(SF) sits within the 747-200 family lineage, offering long-range heavy-payload capability that historically served major cargo operators and integrators. Its four Pratt & Whitney JT9D-70A engines produce substantial thrust (51,140 lbf each), situating the type for transcontinental and intercontinental cargo missions where high deck capacity and palletized loading are prioritized. Competing models in the heavy freighter niche include later 747 variants and widebody freighter conversions; buyer and charter demand for older 747-200SF airframes tends to hinge on remaining structural life, maintenance status, and the availability of JT9D spares and overhaul support. Resale and continued operation considerations for this specific airframe are influenced by its trustee ownership, U.S. registration, and the economics of operating a 1979-build converted freighter.
