RESEARCH NOTES

About N12122

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

Overview

This airframe, registered as N12122, is an Embraer-built regional jet: the Embraer ERJ-145XR manufactured by Embraer S.A. in 2003 with serial number 145684. The aircraft is owned by United Airlines Inc, a corporation based in Chicago, IL, US, and carries a US civil registration. The operational record for this specific airframe centers on short- to medium-haul regional services typical of ERJ-145 operators; ownership is held by the corporate entity United Airlines Inc and there are no public indications of recent registry transfers. Valuation and detailed condition reports for this airframe are not published.

Operations & Cabin

Configured in a high-density regional layout accommodating approximately 50-55 economy seats, this ERJ-145XR features a forward galley and an aft lavatory consistent with regional airline operations. The avionics fit is a typical ERJ-145 installation with a Honeywell Primus/Primus 1000-style integrated suite, supporting regional IFR routings and common airline operational procedures. With a 2,000 nm range and a cruise speed near 470 kts, the airframe is suited to multi-leg regional schedules, feeder services into hub airports, and thin transcontinental sectors within its performance envelope. Based on the owner’s location in Chicago, IL, the aircraft’s primary operational base would likely support short-haul trunk and spoke missions; maintenance considerations follow standard ERJ-145 XR practices, including engine-specific service for the Rolls-Royce AE 3007 series and component support for Honeywell avionics.

Model & Market Context

The Embraer ERJ-145XR family occupies the regional jet niche for 50-55 seat operations, offering extended-range capability compared with base ERJ-145 variants. Competitors in the same sector historically include smaller variants of regional jets and high-capacity turboprops; demand has been driven by regional airlines and major carriers operating dense short-haul networks. From a resale and maintenance perspective, the XR’s Rolls-Royce AE 3007 engines and Honeywell integrated avionics are common support items, but marketability depends on fleet commonality, interior density (this example’s high-density layout), and remaining calendar/flight-cycle life for a 2003-built airframe.
