N405CK

The airframe bearing tail number N405CK is a Boeing-built 737-436(SF) line number 25407, completed in 1991 by manufacturer Boeing. It is owned by Kalitta Charters II (a corporation based in Ypsilanti, MI, US) and operates under a United States registration. The airframe is configured as a main-deck freighter following an SF conversion and is noted in records as a US-registered freighter with crew seating only. Condition and market valuation details are not published in the provided data.

This specific Boeing 737-436(SF) is fitted as a main-deck freighter (SF conversion) and retains only crew seating on board, indicating its primary mission is cargo carriage rather than passenger service. Operated from the owner’s base in Ypsilanti, MI, US, the aircraft’s configuration supports short- to medium-range cargo routes consistent with its published range of 2,060 nm and cruise speed of 473 kts. The twin CFM56-3C1 engines, each rated at 23,500 lbf, provide the thrust profile used for typical regional and domestic freighter sectors up to a service ceiling of 37,000 ft. Maintenance considerations for this airframe follow freighter-conversion regimes and operator-specific practices; specific avionics fit or recent maintenance status are not provided in the supplied data.

The 737-400 series airframe, as represented by this 737-436(SF), occupies a niche in the converted main-deck freighter market for short- to medium-haul cargo operations where a moderate payload and frequent rotations are required. Competing types in the same operational window include other 737 Classic conversions and smaller narrowbodies adapted for freighter work; buyer demand typically favors reliable mission completion and ease of parts support for the CFM56-3C1 powerplant. Resale and maintenance considerations for this airframe hinge on conversion history, total cycles and operator maintenance records, factors not specified in the supplied data.
