N423AW

This entry describes airframe N423AW, a Bombardier-built regional jet produced in 2002 with manufacturer serial number 7636. The aircraft is a Bombardier CRJ-200ER (CL-600-2B19) registered in the United States and owned by Air Wisconsin Airlines LLC of Appleton, Wisconsin. As a 50-seat, ER variant of the CRJ-200 family, this airframe has been operated in a single-class high-density configuration typical of regional carriers. Its US registration and corporate ownership indicate continued service in scheduled regional operations rather than private or corporate use.

The cabin of N423AW is fitted in a single-class high-density 50-place regional passenger layout, reflecting typical operator configuration for short-haul, high-frequency routes. Avionics are equipped with the Collins Pro Line 4 suite, consistent with CRJ-200 operator norms and supporting regional airline navigation, communications, and flight management requirements. Operated by Air Wisconsin Airlines LLC from its Appleton, WI base, the aircraft is primarily suited to short- to medium-range scheduled missions connecting regional hubs, where quick turnarounds and high-seat-density usage are standard. Maintenance considerations for this specific airframe align with the CF34-3B1 engine support network and established CRJ-200 airframe inspection intervals; its ER designation provides modest range and weight capability advantages over non-ER variants.

The Bombardier CRJ-200ER serves the regional jet niche for 50-seat markets, offering efficient turbofan performance with CF34 engines and a maximum cruise near 424 kts and service ceiling of 41,000 ft. Competing models historically include smaller regional jets and turboprops that prioritize lower operating cost or higher capacity depending on route density. For operators like Air Wisconsin Airlines LLC, resale and maintenance considerations focus on airframe fatigue life, engine shop visit history for the CF34-3B1, and avionics commonality such as the Collins Pro Line 4, which can influence marketability in the regional used-aircraft market.
