About CAROL
CAROL enhances the database search process on ntsb.gov. You can search data by:
- SIMPLE SEARCH, which allows you to search any of the ten available fields across any mode and to search on the three aviation specific fields
- ADVANCED SEARCH, which allows you to build custom searches by selecting from a variety of investigation and recommendation fields. You can select whether to display results that match any or all of your individual query rules, or group your rules so results match any or all of the multiple rules in your grouping.
- PUBLISHED SEARCHES, which allows you to view already published popular searches on topics such as safety recommendations associated with the Most Wanted List (MWL). These canned searches show dynamic data reflecting current information in the database each time you open them.
CAROL includes both investigative and recommendation data. When using these search options, you first choose whether to view the results as a list of investigations or recommendations. Remember, the recommendations view provides a complete data set. The investigations view only displays the investigative records that have been created in the system. For aviation investigations, records from 2008 through the present are available. For investigations in other modes, data from 2010 through the present is currently being imported into the system.
The CAROL query works with all modern browsers.
See the CAROL Guide for more information on using CAROL and the database fields.
