N406KZ

This entry covers the specific airframe registered as N406KZ, a Boeing-built freighter delivered in 2007 with manufacturer serial number 36133. The airframe is one of the factory-produced 747-400 freighter conversions and is recorded in corporate trust ownership as WILMINGTON TRUST CO TRUSTEE — a corporate trustee based in Wilmington, DE, US. The registration is held in the US, and the aircraft is configured as a main-deck and lower-hold cargo transporter with operational seating only; notable registry entries primarily reflect trustee ownership arrangements rather than an individual operator change. Maintenance and operational oversight typically follow standard heavy-airframe practices for late-production 747-400 freighters of this vintage.

The aircraft is laid out as a main-deck freighter with a side cargo door and additional lower-hold cargo spaces; its internal fitment includes flight and operations seating only for crew and essential operational personnel, consistent with dedicated cargo service. Avionics fit and specific operator-standard mission equipment are not published for this airframe, but its profile suits long-range, high-payload freight missions up to its listed range and cruise speeds. Typical employment would include intercontinental block-hour operations and scheduled or ad hoc cargo charters originating from the trustee’s contracted operator or leaseholder; maintenance considerations align with heavy-airframe checks common to 747-400 freighters, including periodic structural inspections and engine shop visits for the General Electric CF6-80 series powerplants.

The Boeing 747-400F (747-4KZF/SCD) occupies a niche as a large-capacity, long-range freighter within the fixed-wing multi-engine cargo market, offering high payload and main-deck loading capability. Competitors in similar mission sets include other large freighters such as the 747-8F and various widebody passenger-to-freighter conversions. Buyer and lease demand for late-model 747-400 freighters remains driven by cargo volume requirements and route economics; resale and maintenance considerations for this airframe type typically emphasize engine shop visits, structural life limits, and the availability of heavy-component support for CF6-80 series engines.
