N531GJ

This airframe, registered as N531GJ, is a Bombardier-built regional jet of model Bombardier CRJ-550 (CL-600-2C11) with manufacturer serial number 10218. The build year is not published; the aircraft is owned by United Airlines, Inc. (a corporation based in Chicago, IL) and carries a US registration. The airframe is identifiable in operator records by its serial and registration and has the typical configuration and registry profile associated with United-operated CRJ-550s; no additional notable registry actions or transfers are published for this specific tail.

The cabin installed on this airframe follows United’s three-class CRJ-550 layout of 10 First / 20 Economy Plus / 20 Economy (50 seats, three-class layout typical for CRJ-550 in United service), providing a premium regional configuration relative to standard 50-seat regional jets. Avionics are fitted with Rockwell Collins Pro Line 4 typical of the CRJ700-family regional jets, supporting the aircraft’s systems and navigation needs on short- to medium-haul sector operation. Operated from United’s network base (owner location Chicago, IL), the aircraft typically conducts high-frequency regional hub feeding and short transcontinental links within its 1,378 nm range and cruise speed near 447 kts. Maintenance considerations reflect the CF34-8C5 engine family and Pro Line 4 avionics commonality with CRJ700 variants, simplifying spares and line maintenance within the operator’s regional fleet.

The Bombardier CRJ-550 (CL-600-2C11) occupies a niche as a premium 50-seat regional jet derivative of the CRJ700 family, offering enhanced passenger amenities and a three-class cabin while retaining the operating economics of a 50-seat certificate. Competing models and configurations in the regional market include other 50-seat and small 70–90 seat regional jets, but the CRJ-550’s unique cabin mix targets carriers seeking premium regional frequency. Resale and maintenance considerations center on the CF34-8C5 engine commonality and Pro Line 4 avionics, factors that influence operator demand, parts pooling, and lifecycle costs.
