Research on on-object verification requirement evaluation of revised civil aircraft maintenance manual procedure

At present，researches on verification of civil aircraft maintenance manuals are focused on verification method，verification flow，quality control and so on. There are no relevant criteria and flow of on-object verification requirement of revised civil aircraft maintenance procedure，thus some researches are urgent needed. Evaluation criteria and flow of on-object verification requirement of revised civil aircraft maintenance procedure are concluded and summarized by analyzing whether the revised contents of maintenance procedures need to propose an onobject verification requirement or not，and in combination with manual verification experiences during flight test and operation of civil aircraft，also verified with instance. The results show that revision of common information，safety conditions etc. need not propose an on-object verification requirement，but revision of access method，test logic etc，should propose an on-object verification requirement. It will provide convenience for those who write and verify the maintenance manuals，when they make judgment.
