N687SK

This entry concerns airframe N687SK, a regional jet built in 2005 with manufacturers' serial number 10198. The aircraft is a Bombardier CRJ-701 (CL-600-2C10) originally manufactured by Bombardier Inc. and is recorded as owned by SkyWest Airlines Inc, a corporation headquartered in St. George, UT, US. Operated in SkyWest's regional fleet and registered in the United States, the airframe is configured and maintained for scheduled regional passenger service with routine line maintenance consistent with multi-airline regional operations.

The subject aircraft carries a single-class regional passenger layout configured for 69-seat capacity, optimized for short- to medium-haul sectors typical of regional airline networks. The avionics suite in this specific airframe is the Rockwell Collins ProLine 4, providing integrated flight management, navigation, and systems monitoring capabilities suited to commercial regional operations. With a maximum cruise speed of 447 kts and a range of 1,434 nm, the jet is typically deployed on multi-leg, high-frequency routes connecting smaller airports to major hubs; its operational ceiling of 41,000 ft enables efficient climb profiles and enroute performance. Maintenance considerations for this particular airframe follow the GE CF34 family’s established inspection cycles and SkyWest’s corporate maintenance program.

The Bombardier CRJ-701 (CL-600-2C10) occupies the regional jet niche, offering seating for approximately 69 passengers and matching competitors in its class on speed and range. Typical competitors include other 70-seat regional jets and stretched variants from both Bombardier and Embraer families. Demand among regional carriers remains driven by the model’s suitability for high-frequency, short-haul markets and commonality benefits within fleets; resale and maintenance considerations center on airframe hours, CF34 engine condition, and avionics fit such as the installed Rockwell Collins ProLine 4, which affects fleet reintegration and valuation.
