N919FJ

This article concerns airframe N919FJ, a Bombardier CRJ-900ER (CL-600-2D24) built in 2004 with manufacturer serial number 15019. The airframe is registered in the United States and is owned by MESA AIRLINES INC of Phoenix, AZ, US, its corporate owner and principal operator. Notable registry actions include a cabin reconfiguration in 2011 from a Y86 layout to a C9Y70 layout, and the aircraft is commonly operated in single-class high-density configurations. The aircraft is certificated in the fixed-wing multi-engine category and retains avionics typical of its series.

This specific CRJ-900ER, N919FJ, was re-configured in 2011 from a Y86 two-class type arrangement to a C9Y70 layout, reflecting a shift to higher-density single-class seating commonly used by regional operators to maximize revenue per flight. The factory-standard Rockwell Collins Pro Line 4 avionics suite supports regional operations and is consistent with airline crew training and common-parts logistics. With a 95-seat nominal capacity but frequent operation in mid-80s to low-90s high-density layouts, this airframe typically serves short- to medium-haul regional routes from its Phoenix base, performing frequent daily cycles and subject to the maintenance profile associated with high-utilization commuter service.

The CRJ-900ER family occupies the regional jet performance niche between smaller regional jets and larger single-aisle airliners, offering a design cruise near 447 kts and a practical ceiling of 41,000 ft, paired with twin CF34-8C5 turbofans. Competing models include other 70–100 seat regional jets from regional and narrowbody manufacturers; demand for airframes like N919FJ is driven by carriers seeking capacity on short- to medium-haul routes. Maintenance and resale considerations for this 2004-build aircraft reflect its high-cycle regional operation, cabin-density conversions, and the established avionics and engine commonality within the CRJ-900 series.
