A systematic working mechanism for risk identification in conceptual design phase of civil aero-engine was established to promote efficient type certification with corrective actions. The mechanism comprehensively categorized the risks of regulations

means of compliance

implementations and critical technical points

by which the regulation terms information table was developed. 278 potential risks were identified by regulation terms information table utilization in specific civil aero-engine model. In addition

the potential risk of typical rotor integrity regulation in process from requirement definition to design implementation was analyzed in detail

which verified the mechanism and regulation terms information table.
