N653RL

This airframe, registered as N653RL, is a Boeing 737-300 built in 1997 with manufacturer's serial number 28398. It is a passenger-to-freighter conversion variant listed as Boeing 737-300 (737-3H4(SF)) and is registered in the US. Ownership records identify the current titleholder as BANK OF UTAH TRUSTEE, a corporation based in Salt Lake City, UT, US; this trustee ownership indicates financial or leasing arrangements rather than direct airline operation. Operator and base details are not published, and notable registry actions beyond the recorded owner are not published.

The airframe has been modified to a converted freighter configuration (SF), with passenger seats removed and a cargo-centric cabin layout tailored for bulk or palletized freight. Avionics fit is typical of late‑1990s Boeing 737-300 series retrofit standards, with specific equipment not published for this individual airframe. Typical mission profiles for this configuration emphasize medium-range, high-utilization trunk and feeder cargo services within the aircraft’s 2,255 nm range and cruise speed of 430 kts, operating up to a service ceiling of 37,000 ft. Maintenance considerations for this specific aircraft include standard 737-300 generation heavy airframe and CFM56-3B1 engine shop visits and the special inspection regimes associated with freighter conversions; operator base and line maintenance providers are not published.

The Boeing 737-300 SF occupies a niche as a low‑deck, single-aisle freighter suitable for regional and short transcontinental cargo operations, leveraging the widespread support network for older 737 Classics. Competitors in the secondary freighter market include converted Airbus A320ceo family and smaller ATR freighters for short sectors, though the 737-300 offers higher cruise speed and payload for medium-range legs. Buyer and charter demand for Classic-series freighters tends to favor users valuing commonality and lower acquisition cost; resale and maintenance considerations reflect the airframe’s 1997 build year, legacy systems, and remaining structural fatigue life associated with its serial 28398.
