N8731J

This airframe, registered as N8731J, is a Boeing 737-8 MAX built by Boeing in 2018 with manufacturer serial 42550 / 7321. The airframe is owned by SOUTHWEST AIRLINES CO, a corporation located in Dallas, TX, US, and carries a US registration. The aircraft’s documented history centers on commercial mainline use by its corporate owner; title and operational control are recorded to SOUTHWEST AIRLINES CO in Dallas. Condition and valuation highlights for this specific airframe are not published in the supplied data.

The airframe is configured in a single-class layout with 175-economy seats consistent with the airline standard for Southwest 737 MAX 8s, supporting high-density short- to medium-haul mainline schedules. Avionics on this individual aircraft follow the typical fit for 737 MAX-series operators, identified as Collins Aerospace equipment, which integrates with airline operations and maintenance programs. With a range of 3,550 nm and a cruise speed near 453 kts, the aircraft is suited to nonstop domestic and transcontinental sectors within the owner’s route network. Maintenance considerations reflect its role as a single-type fleet asset for the named corporate operator, emphasizing standard airline heavy-check cycles and parts support tied to the LEAP-1B engine family.

This instance of the Boeing 737-8 MAX sits within the MAX-series performance niche as a fixed-wing multi-engine jet optimized for high-capacity mainline service, as indicated by its 175-seat single-class cabin and technical specs. The twin CFM International LEAP-1B engines rated at 28,690 lbf each provide the thrust and efficiency characteristics associated with MAX-series operations. Buyer, lease, and secondary-market considerations for an aircraft with these attributes typically emphasize fleet commonality, engine program support, and avionics fit—here noted as Collins Aerospace—which influence maintenance planning and resale dynamics for the airframe.
