N8663A

This airframe, registered as N8663A, is a Boeing 737-8H4 (737-800) built in 2015 with manufacturer serial number 36902. The aircraft is owned by UMB BANK NA TRUSTEE, a corporate trustee based in Salt Lake City, UT, US, and is registered in the US. Its documented configuration is an all-economy, 143-seat layout described as the Southwest configuration, and the airframe is notable for being a late-production 737-800 series example delivered in the mid-2010s. Held in trust by a corporate trustee, the airframe’s ownership structure is typical of aircraft placed in financial or lease custodial arrangements, though specific operator assignments and transactional history beyond trustee ownership are not published here.

The aircraft is fitted in an all-economy cabin of 143 seats reflecting the Southwest configuration, optimized for high-density short- to medium-haul operations. Typical mission profiles for this airframe class include domestic and regional trunk routes consistent with a 3,115 nm maximum range and a cruise speed of 444 kts, allowing flexible utilization across multi-leg schedules. Avionics and specific line-fit options are not published here; maintenance considerations are driven by the commonality of the CFM56-7B engine family and the 737NG airframe, which support established aftermarket support and MRO practices. Trustee ownership can affect maintenance record access and lease arrangements, and this airframe’s late-2010s manufacture date suggests remaining structural and systems life that aligns with typical airline utilization cycles.

The Boeing 737-800 belongs to the 737 Next Generation family, occupying a performance niche for single-aisle, medium-range operations with strong seat-mile economics in high-density configurations. Competing models in its segment have historically included Airbus A320ceo variants; demand from carriers and leasers has centered on reliability, fleet commonality, and secondary-market liquidity. For this specific airframe—serial 36902, year 2015, engines CFM56-7B27E, and a 143-seat all-economy fit—resale and lease considerations will be influenced by the high-density cabin layout, engine maintenance status, and the trustee ownership structure that can simplify or complicate title transfer and remarketing.
