2. Locate the specified director level, detail level, or trouble-clearing procedure. All
procedures are in numerical order, regardless of type. The TOP procedures in this
manual are of the following four types:
• Non Trouble Clearing Procedure (NTP): A director level procedure that lists normal
work items to be performed that are not trouble clearing procedures.
• Trouble Analysis Procedure (TAP): A director level procedure that provides step-by-
step instructions to locate and fix trouble.
• Detailed Level Procedure (DLP): Detailed step-by-step instructions or procedures.
• 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 director level procedure to another director level procedure,
in most instances it will not be necessary to go back to the first director level procedure
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 appropriate 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.
