The Accident/Incident Data System (AIDS) database contains data records for general aviation and commercial air carrier incidents since 1978. The ASIAS database for AIDS contains incidents only because ASIAS uses the National Transportation Safety Board (NTSB) accident database as the primary source for accident information. The information contained in AIDS is gathered from several sources including incident reports on FAA Form 8020-5.

The FAA aircraft registry is a data system used to record and track civil aircraft registered in the United States. Registration occurs at the Federal Aviation Administration in Oklahoma City where the appropriate information is obtained and recorded from the aircraft purchaser. The database is updated in real time as the registry staff obtain and enter the data into the data system. The Registry maintains the permanent records of over 320,000 active civil aircraft and provides approximately 700 copies of aircraft records daily for review to users of the Public Documents Room located in the Registry Building at the Mike Monroney Aeronautical Center in Oklahoma City, Oklahoma.

The Aviation Safety Reporting System (ASRS) receives, processes, and analyzes reports of unsafe occurrences and hazardous situations that are voluntarily submitted by pilots, air traffic controllers, and others. Information collected by the ASRS is used to identify hazards and safety discrepancies in the National Airspace System. It is also used to formulate policy and to strengthen the foundation of aviation human factors safety research.

The Bureau of Transportation Statistics (BTS) database contains traffic and capacity statistics on individual Air Carrier operations. BTS is an administration under the Department of Transportation (DOT), at a similar organizational level as the FAA. During the 1970s, when the Civil Aeronautics Board (CAB) was disestablished, the CAB Bureau of Accounts and Statistics came to be what is now the BTS office of Airline Statistics.

The National Transportation Safety Board (NTSB) Aviation Accident and Incident Data System contains information collected during an NTSB investigation of an accident or incident involving civil aircraft within the United States, its territories and possessions, and in international waters. The NTSB Board is an independent Federal agency that investigates every civil aviation accident in the United States and significant accidents in the other modes of transportation, conducts special investigations and safety studies, and issues safety recommendations to prevent future accidents.

The National Transportation Safety Board (NTSB) uses the information it gathers during accident investigations and the determination of probable cause to make safety recommendations to all elements of the transportation industry. While the recipient of a recommendation does not have to implement the proposed action, it does have to respond formally to the recommendation and specify what action is or is not being taken and why. This database contains the NTSB recommendations to the FAA and the FAA responses. Please be advised that The data for this system has not been refreshed this month due to technical difficulties. We are working to restore services and will update the system as soon as it becomes available.
