N17403

This airframe, registered as N17403, is a Boeing-built single-aisle jet of the Boeing 737-9 MAX variant completed in 2025 with manufacturer serial number 67645. The aircraft is held in trust by UMB BANK NA TRUSTEE (a corporation located in Salt Lake City, UT) and is registered in the US. The airframe is a new-build 2025 delivery with a standard ownership arrangement under a trustee entity; ownership recorded under UMB BANK NA TRUSTEE, Salt Lake City, UT is the primary documented change in its early lifecycle. Condition and formal valuation have not been published publicly for this specific airframe.

The cabin configuration is reported in a two-class United Airlines layout with C20/Y159 (approximately 179 total seats), indicating a single-aisle, high-density passenger role for short- to medium-haul operations. With a design cruise of 453 kts and a range of 3,300 nm, the aircraft is suited to domestic and transcontinental missions within the continental US and similar markets. As a 2025-build airframe, routine entry-into-service maintenance and warranty provisions typical of new deliveries would apply; the twin CFM International LEAP-1B powerplants are the installed engine type and define the primary maintenance and overhaul considerations for this specific aircraft. The trustee ownership suggests the airframe may be leased or financial-asset managed rather than operated directly by the trustee.

The Boeing 737-9 MAX represented by this airframe occupies a high-capacity single-aisle segment characterized here by a 179-seat two-class layout and extended single-leg capability to 3,300 nm. Its performance envelope — including a 41,000 ft service ceiling and cruise near 453 kts — reflects the airframe’s role in bridging short- and longer domestic sectors while maximizing seat count. For this specific serial and registration, market considerations will center on lease arrangements, fleet integration with operators using the United configuration, and typical maintenance trajectories tied to the LEAP-1B engines and 2025 production-standard fittings.
