N37257

This airframe, N37257, is a Boeing 737-8 MAX manufactured by Boeing in 2021 with serial number 43442 / 8111. The aircraft is held in corporate trust, owned by WILMINGTON TRUST CO TRUSTEE (Wilmington, DE, US), and is listed on the US civil register. Documented as a mainline passenger airframe configured for United Airlines' single-aisle operations, the example carries a reported market valuation of $50,000,000 and reflects a contemporary production 737 MAX in typical commercial service condition for its model year. Registry entries identify the US registration and serial linkage; no other public transfer events are published in the supplied data.

The airframe is outfitted in a Mainline United Airlines single-aisle passenger layout, reported at approximately 175 seats, indicating a standard short- to medium-haul high-density configuration. Typical mission profiles for this fitted 737-8 MAX include domestic and transcontinental scheduled services within the aircraft's 3,550 nm range and cruise speeds near 453 kts, operating to and from United's network airports. Avionics and systems are those standard to factory-delivered 737-8 MAX units of the 2021 production batch; maintenance considerations follow manufacturer and operator program norms for LEAP-1B–powered MAX aircraft, including engine-specific shop visit planning and airframe structural inspections aligned to airline heavy maintenance cycles.

The Boeing 737-8 MAX occupies the single-aisle narrowbody performance niche for airlines seeking improved fuel efficiency and range over prior-generation 737 models. With two CFM International LEAP-1B engines delivering 27,300 lbf each and a typical capacity near 175 seats, it competes with contemporary narrowbodies in the same mission band. Buyer and lessee demand for late-production 2021 MAX airframes is influenced by operator fleet commonality, residual value estimates such as the stated $50,000,000, and continuing aftermarket considerations tied to LEAP-1B engine maintenance and airframe configuration.
