FIG. 9 is a flow chart of a process of applying a scanner in the method of managing an aircraft maintenance process according to the present invention.

In the aircraft maintenance process management method according to the present invention, the inspection card used at the job site is scanned and converted into a file to manage the working document history.

To do this, a check card, which is a work document, is first scanned through the document scanner 231 (S100).

The check card scanned in step S100 is converted into a PDF and a document file (S110), and a naming number is generated (S120). Namely, the data of the nickname is read out from each process work performance database to generate the nickname.

In accordance with the naming number generated in step S120, it is possible to manage the performance of the process operation for each worker in the field (S130).

With such performance management, it is possible to establish a database for each part exchange and work date and time of each worker (S140, S150). That is, the status of the parts can be managed.
