The U.S. Federal Aviation Agency has approved the escalation of the maintenance intervals in the Bombardier CRJ700, CRJ900, and CRJ1000 to 800 flight hours for A Checks and 8,000 hours for C Checks, the Canadian manufacturer announced Monday. The changes extend the models’ line maintenance and heavy maintenance intervals for the second time since the launch of the CRJ700 in 1997, when specifications called for A Checks every 400 hours and C Checks every 4,500 hours.
