Bombardier Proposes CSeries Maintenance Intervals
Bombardier has proposed establishing 850-hour intervals for CSeries aircraft line maintenance checks (A Checks) and 8,500-hour intervals for the new airliner’s base maintenance checks (C Checks), the manufacturer announced at its May 28 European Regional Review in Munich, Germany. Engaged in developing a CSeries maintenance program based on Maintenance Steering Group 3 (MSG-3) since October 2010, Bombardier claims the “longer” intervals will minimize downtime and result in “more competitive” maintenance costs for operators.
The maintenance program for the CSeries remains under development using the MSG-3 process, in which analysis for systems, powerplant and structures undergoes review during working groups and approval by the CSeries Industry Steering Committee (ISC). Following a series of meetings with working groups and the ISC, Bombardier must submit a Maintenance Review Board Report to the authorities for acceptance before entry-into-service next year.
