N732CK

This airframe, registered as N732CK, is a Boeing-built freighter conversion of the Boeing 737-405(SF) completed in 1989 with manufacturer serial number 24271. The airframe is owned by KALITTA CHARTERS II LLC (an LLC based in Ypsilanti, MI, US) and carries a United States registration. The airframe's paperwork and registry entries reflect its conversion to a main-deck cargo role and ongoing use in freight operations. Maintenance status and market valuation figures are not published in the supplied data, but the aircraft’s configuration and age place it within the active narrowbody freighter pool operated by U.S.-based charter and cargo specialists.

This specific 737-400 series airframe was converted to a freighter with a main-deck cargo cabin layout, replacing passenger seating with palletized and containerized cargo capability. The conversion implies structural reinforcement and a large forward or forward-and-aft main deck cargo door consistent with SF (special freighter) conversions, supporting typical short- to medium-range express and ad-hoc charter cargo missions. Operated from the owner’s U.S. base, the aircraft’s mission profile centers on time-sensitive freight routes within its 2,060 nm range and at cruise speeds near 485 kts. Routine maintenance considerations for this airframe would focus on aging-structure inspections and continued support for the two CFM56-3C1 turbofan engines.

The Boeing 737-405(SF) sits in the narrowbody freighter niche offering efficient short- to medium-haul payload capability drawn from a high-production passenger derivative. Competing options include converted regional jets and other 737 Classics; demand is typically driven by express freighter operators and charter cargo firms. Resale and maintenance considerations for a 1989-built 737-400 freighter emphasize component life limits, ageing corrosion checks, and enginespecific support for the CFM56-3C1 series when evaluating vessel utility and remaining economic life.
