N331CK

This airframe is registered as N331CK, a Boeing-built airliner completed in 1987 with manufacturer serial number 23747. It is a converted freighter variant listed as a Boeing 737-300 (converted freighter, B737-300SF/BDSF) and currently owned by KALITTA CHARTERS II LLC (an LLC based in Ypsilanti, MI, US). The airframe carries a US registration and has been reconfigured from passenger service to a main-deck pallet/bulk cargo arrangement, a significant modification that marks its most notable registry action as conversion to a Special Freighter (BDSF) configuration. Condition notes specific to this airframe are limited in the record, but its ownership by a charter-focused LLC indicates active commercial cargo deployment rather than storage or salvage.

The cabin of N331CK is a converted freighter layout with the passenger cabin removed and a main-deck pallet/bulk cargo configuration installed, reflecting its role in cargo carriage rather than passenger transport. Typical mission profiles for this airframe would center on short- to medium-range freight routes within its 2,255 nm range and at an operational cruise speed near 430 kts, operated from the owner’s home base in Ypsilanti, MI, US or other regional cargo hubs. Avionics fitment is not published in the provided data; maintenance considerations focus on the airframe age (built 1987) and the CFM56-3B2 engine type, both of which are well understood in the aftermarket but require ongoing life-limited component tracking and freighter conversion inspection regimes.

The Boeing 737-300 converted freighter occupies a niche for operators needing a rugged single-aisle freighter with modest payload and range for intra-continental services. Competing platforms include older narrowbody freighter conversions and turbofan-powered freighter derivatives; demand tends to come from cargo specialists and charter operators who value lower acquisition cost over the efficiency of newer models. Maintenance and resale considerations for this airframe reflect its 1987 vintage, the widespread familiarity with the CFM56-3B2 engines, and the market dynamics for B737-300SF/BDSF types, where lifecycle costs and structural fatigue assessments are key factors for buyers and operators.
