As we all know, the human factor is one of the significant problems which would increase the number of times that the aircraft have to schedule maintenance. In my research paper, I would be going to do some research on what kind of human factors would lead the aircraft to have to schedule unscheduled maintenance. Also, I would be going to doing some research on how could aviation maintenance management helps to low down the rate of the unscheduled maintenances that were caused by human factors.
