This application describes tools for online tracking of life-limited parts. These tools may support methods that include receiving queries, and searching databases in response to the queries. These methods may integrate results of the searches into reports that provide comprehensive histories of life-limited parts for installation within vehicles, and may report these integrated results. To build these databases, other methods may receive information relating to the life-limited parts from a variety of sources, load the information into suitable databases, and integrate this information as provided by the various sources. Other methods may also evaluate whether the parts have any permitted life remaining. These tools may also provide databases that store serial numbers associated with the parts, store physical locations of the parts at various times, indicate who owned the parts at different times, and include remaining life records that indicate any permitted life remaining for the parts.
