N329MS

This entry concerns airframe N329MS, a 2007-built Bombardier regional jet identified as a Bombardier CRJ-900LR (CL-600-2D24), serial number 15126. The airframe is recorded as owned by Mesa Airlines Inc., a corporation based in Phoenix, AZ, US, and is registered in the US. The type certificate and build designation place this airframe within Bombardier Inc.'s CRJ-900 long-range variant production run; its year of manufacture and serial number are primary identifiers used in maintenance tracking and regulatory filings. Notable registry and operator records for this specific tail number reflect its role as an operator-configured regional passenger transport under Mesa Airlines' corporate ownership.

The airframe is outfitted in a 76-seat regional passenger layout (operator-configured) cabin consistent with short- to medium-haul regional operations. As a fixed-wing multi-engine aircraft, it is intended for scheduled regional passenger service operated from Mesa Airlines' Phoenix, Arizona base. Typical mission profiles for this airframe, given its 1,836 nm range and 448 kt cruise, emphasize higher-frequency, short- to medium-length sectors where a 76-seat capacity aligns with regional demand. Maintenance and operational scheduling for this airframe are managed against the engine type GE CF34-8C5 and the 2007 manufacture date, which together inform component life-limited parts, inspection intervals, and operator configuration records.

The Bombardier CRJ-900LR (CL-600-2D24) airframe represented by N329MS occupies a regional jet niche defined by a balance of capacity (76 seats), cruise speed (448 kt), and extended regional range (1,836 nm) relative to single-aisle feeder aircraft. Its twin GE CF34-8C5 engines, each rated at 14,510 lbf, define the propulsion and maintenance baseline for this serial-numbered airframe. The combination of a 2007 build year, documented serial 15126, and corporate ownership by Mesa Airlines Inc. are central to any assessment of operational availability, maintenance status, and regulatory history for this specific CRJ-900LR.
