Aviation psychologists do believe that when a person makes a mistake, especially if that mistake is a violation of procedures, then it is not the first time that they are doing it. Also it is believed that in an organization if one person is doing something without check and balance, then there are very strong chances that other people will also be doing it – indicating a poor safety culture in that organization. The question is: who or what allows the safety culture to get destroyed?
The aircraft data, which is downloaded after the flight has the answer. If the accountable managers of safety and operations do not do their work and do not give proper feedback to correct such pilots then as per human nature the habit patterns will continue to erode. So much so that no one in that organization will be held responsible.
It is immensely important to know that aviation is based on a block-building approach of managerial hierarchy. If any of those managers are not doing their job then the safety culture will immediately collapse and the results will be deadly.
