d)Trouble Analysis Data (TAD) A trouble clearing aid containing non-procedural data.

3.Perform all the items in the director level procedure (NTP ‘or TAP) in the order listed unless sent to another director level procedure. When a director level procedure is finished, the task is completed. When more detailed information is required, the reader will be sent to a DLP. A DLP may also direct the reader to another DLP.

Note: When a DLP is complete, return to the procedure that preceded the DLP.

Note: When sent from one DLP to another DLP, in most instances it will not be necessary to go back to the first DLP after competing the second.

4.In some procedures, it will be necessary to verify that certain responses have occurred. If the expected response is not observed, refer to the TAP. If additional data is required such as a schematic diagram, line drawing, tabulated data, maintenance philosophy, or trouble clearing strategy, the reader will be sent to a TAD.

Find the task to be performed in either the Indexed Task List, or the Alphabetical Task List. These will refer to NTP, DLP, or TAP procedures.
