N8673F

This airframe, registered N8673F, is a Boeing 737-8H4 (737-800, winglets) completed in 2015 with manufacturer serial number 36937. The aircraft is held in trust by UMB BANK NA TRUSTEE (a corporation based in Salt Lake City, UT, US) while operated in a commercial passenger configuration for Southwest Airlines under a United States registration. Registry records indicate standard commercial certification for fixed-wing multi-engine transport in the US registry, and the airframe’s mid-2010s build places it among late-production Next Generation series 737-800s with winglets. Condition and valuation details are not published beyond its current trust ownership and active passenger role.

The airframe is outfitted in a 143-seat single-class (Southwest Airlines) cabin layout optimized for high-density short- to medium-haul service typical of its operator. Avionics conform to Boeing 737-800 line standards for the NG family, supporting typical domestic rotation patterns with rapid turnaround operations. With a cruise speed of 440 kts and range of 3,060 nm, the aircraft frequently serves transcontinental and high-frequency trunk routes from Southwest’s operational bases. Maintenance considerations reflect common NG-series practices, including CFM56-7B engine shop visit cycles and winglet-related aerodynamics benefits; trustee ownership implies centralized asset management and potential leasing arrangements.

The Boeing 737-8H4 (737-800) sits in the single-aisle, medium-range market niche, offering operators a balance of capacity and operating economics for dense short- and medium-haul networks. Competing models include later 737 MAX variants and the Airbus A320 family in similar seat-count configurations; resale and lease demand for NG-series airframes remains robust for operators valuing proven reliability and commonality. For this specific airframe—serialized 36937 and built in 2015—maintenance, life-cycle component status and CFM56-7B engine status are primary resale considerations for prospective buyers or lessors.
