The National Transportation Safety Board announced updates to CAROL, the database for NTSB investigations, and aviation investigation search functions on NTSB.gov. CAROL now includes an expanded aviation dataset for information on investigations from 1962 to present. 

Users will notice a new landing page for CAROL that includes links to all search pages. The “Simple Search” and “Advanced Search” options have been renamed to “Basic Investigation and Recommendation Search” and “Custom Search Builder,” respectively. Custom Search Builder allows users to build a search for investigations or recommendations using any parameters available in the database. 

The NTSB also relaunched the Aviation Query page, now called Aviation Investigation Search, on NTSB.gov. The relaunched page allows users to search all aviation investigations and includes expanded download capabilities for CSV and JSON downloads, which will now include hyperlinks to the dockets and reports. 

These updates are directly based on user feedback. NTSB continues to welcome input and comments on CAROL and search functionalities. Users can submit feedback to [email protected].

CAROL allows users to conduct investigation searches for all modes (rail, pipeline, hazardous materials, marine, highway and aviation) and to move seamlessly through information.
