Requirement analysis and architecture of maintenance,repair and overhaul/operations information system for helicopters

To push advanced concepts of modern condition-based maintenance and improve the helicopter attendance rate and operational readiness,after analyzing the requirements of helicopter Maintenance,Repair and Overhaul/Operations(MRO)information system,information and network technology was applied in helicopter maintenance system,and a maintenance policy supporting regular maintenance and state maintenance was proposed.Based on Open System Architecture for Condition-Based Maintenance(OSA-CBM),the MRO information system architecture for helicopters was constructed.Finally,deployments of helicopter MRO system were discussed.
