RESEARCH NOTES

About N17431

Compiled with AI assistance from the public sources listed below, November 2025. Not checked against the aircraft's logbooks.

Overview

This airframe, registered as N17431, is a Boeing 737 MAX 9 built by Boeing with serial number MSN 43528. It is owned and operated by United Airlines, Inc., a corporation based in Chicago, IL, US, and is registered in the US. The airframe conforms to the standard narrow-body MAX series production and has been integrated into United's fleet for dense short- to medium-haul operations. Operator deployment reflects United’s configuration and route planning choices rather than bespoke modifications to the airframe. Condition and valuation details are operator-managed and not published in the supplied data.

Operations & Cabin

The cabin is laid out in a typical two-class arrangement; the general MAX-9 cabin option range is 178-193 seats, and this airframe is fitted with United’s denser two-class 178-seat layout. The flightdeck is equipped with a Boeing-standard MAX flightdeck featuring four large-format displays with a Rockwell Collins-style presentation, supporting modern avionics workflows and crew interoperability across the MAX fleet. Operationally, this MAX-9 is suited to continental transcontinental and high-frequency short- to medium-range routes consistent with United’s network strategy out of Chicago and other U.S. hubs. Maintenance considerations follow Boeing and CFM maintenance programs for the MAX family and LEAP-1B engines; specific line- and heavy-maintenance status is not published in the provided data.

Model & Market Context

The Boeing 737 MAX 9 occupies a performance niche as a stretched single-aisle offering extended range and higher capacity than earlier 737 variants, targeting dense short- and medium-haul markets. Competing models include larger single-aisle types from competitors in similar capacity and range brackets. Demand from major network carriers for this model typically emphasizes fleet commonality, seat density options, and engine support agreements; resale and maintenance considerations hinge on operator configuration, engine shop visit cycles for the LEAP-1B, and residual market preferences for MAX-series aircraft.
