Air Transportation Oversight System ATOS

Under ATOS, operations of an airline are divided into 7 systems, 14 subsystems, and 88 underlying component elements, which provide a good structure for identifying risks or areas of concern, performing surveillance, and collecting data [6]. Additional information on ATOS is available in Wells and Rodrigues [6]. 

The Accident/Incident Reporting System was developed by the National Transportation Safety Board (NTSB), and it contains information on all known civil aviation accidents that have occurred in the United States over the years. This database or system may simply be called the official repository of aviation accident data and causal factors. 

The database data are classified under the following nine categories [6]
