Bombardier CRJ-900 Accessory Refurbishment Services
Introduced in 2003, the Bombardier CRJ-900 extended the successful CRJ family with increased capacity while maintaining the operational economics and airport compatibility that made regional jets successful. The CRJ-900's jet performance enables faster block times than turboprops on routes over 300 miles, while its size allows service to smaller airports and thin routes that larger narrowbody aircraft cannot serve profitably.
