N734CK

This entry covers airframe N734CK, a Boeing-built transport completed in 1993 as serial number 25858. The type is recorded as Boeing 737-436 (737-400 SF freighter conversion), and the aircraft is registered in the US. It is owned by Kalitta Charters II LLC, a corporation based in Ypsilanti, MI, US, and the airframe reflects a main-deck cargo role following its documented 737-400SF conversion. Registry and valuation specifics beyond ownership and configuration have not been published.

The cabin of N734CK is configured as a freighter with a main-deck cargo layout resulting from the 737-400SF conversion; passenger seating capacity is recorded historically as 149 but the present operational fit is focused on cargo carriage. As a corporate-operated aircraft based under Kalitta Charters II LLC in Ypsilanti, MI, its mission profile centers on short- to medium-range freight runs consistent with the 2,080 nm range and 439 kts cruise performance. Maintenance considerations for this airframe include the implications of the freighter conversion on structural inspections, door and floor reinforcement, and supplemental airworthiness paperwork typical for Supplemental Freight (SF) conversions. No specific avionics fit or line-item maintenance history has been published for this registration.

The Boeing 737-400 family occupies a niche for operators seeking a common large narrowbody freighter with economical short- to medium-range capability; N734CK with its CFM56-3C1 powerplants and 23,515 lbf thrust rating exemplifies the type’s performance balance. Competing options in the same market include other converted 737 Classics and regional narrowbody freighters, with demand driven by cargo operators valuing main-deck capacity and fleet commonality. Resale and maintenance considerations for this specific airframe hinge on conversion condition, remaining structural life, and continued support for the CFM56-3 series engines.
