The US Federal Aviation Administration (FAA) has recently made available three searchable aviation databases: NTSB (National Transportation Safety Board) Accident/Incident Database, FAA Incident Data System, and NTSB Recommendations to the FAA. The databases are updated monthly and are available back to 1983, 1978, and 1963 respectively. The first two can be searched via a form that allows a combination of user entries and choices from drop-down menus. Interested users are strongly encouraged to read the "Learn About the Databases" section, as well as the information about each variable before using the databases. The site also contains a brief aviation glossary and FAA regulations from the US Code of Federal Regulations. Note that the site "supports Netscape and Microsoft Internet Explorer only."
