The aircraft has been modified to a freighter configuration with main-deck cargo capability while retaining documentation that its original certified passenger layout accommodated 149 seats. As operated by Kalitta Charters II LLC, mission profiles for this specific airframe are centered on cargo carriage consistent with its freighter conversion, operating from its owner’s base in Ypsilanti, MI, US under US registry. Cabin and cargo arrangements reflect the conversion note to main-deck cargo; original passenger capacity is retained in historical records while current operational cabin is dedicated to freight.

The Boeing 737-436(SF) represented here is part of the 737 Classic family, with performance parameters shown by its CFM56-3C1 engines and mid-range cruise and ceiling figures appropriate to short- to medium-haul cargo missions. In the marketplace, Classic-series freighter conversions are commonly positioned to satisfy regional and domestic cargo demand where straightforward systems and proven airframes are preferred. Ownership by a US-based charter and cargo operator underscores typical demand drivers for such conversions, and resale or maintenance considerations hinge on documented conversion status, engine type, and airframe vintage as indicated by the 1992 build year and serial 25849.
