N503KW

This article covers the specific airframe bearing tail number N503KW, a Boeing-built widebody registered in the US and completed in 1998 with manufacturer serial number 28553. The airframe is a member of the Boeing production line designated Boeing 767-346 and is recorded as owned by ALTA AIRLINES HOLDINGS LLC, a corporation based in Salt Lake City, UT, US. The ownership record reflects a corporate holding rather than individual or flag carrier operation, and the aircraft’s registration and corporate domicile indicate U.S.-based operational oversight and regulatory jurisdiction. Notable registry details include the preserved manufacturer serial and the current corporate registration; other valuation or condition specifics have not been published.

The subject airframe, N503KW, in its role with ALTA AIRLINES HOLDINGS LLC, would typically be configured and maintained under commercial or corporate operational standards appropriate to a Boeing 767-300 series derivative. Cabin layout, seating count, avionics fit, and range-specific outfitting for this individual airframe have not been published, though operators of this model commonly employ mixed-class configurations and long-range fuel planning for transcontinental and international routes. Maintenance considerations for this specific airframe are governed by its U.S. registration and the operator’s continuing airworthiness program; no unique amenities or modifications for N503KW have been disclosed in the public data provided.

The Boeing 767-346 belongs to the 767 family, a twin-engine, widebody series positioned for medium- to long-haul routes where its twin CF6-series powerplants offer a balance of efficiency and payload capability. In the secondhand market, airframes like 28553 attract interest from passenger carriers, charter operators, and cargo conversions, with resale and maintenance considerations influenced by airframe age (built 1998), engine type (CF6-80C2B2), and corporate ownership status. Competing types in its niche include other twin widebodies offering similar seat-mile economics; specific buyer demand for this airframe would depend on disclosed condition, avionics standardization, and remaining structural life, none of which are published here.
