Narrative:

Mistakenly taxied a few feet past hold short line while trying to find undocumented taxiway (not on airport diagram). It would be helpful if airport diagram updated to show exit off runway 7L to south. As is often the case, distraction was a significant factor. To prevent recurrence, must remain more alert especially if non-graphed txwys intersect runways. Callback conversation with reporter revealed the following information: the reporter was using the government chart. He said that he was approaching the runway 25R from the south on a taxiway that intersects the runway at about the same point as taxiway 5N does on the north side of the runway. He alleges that the taxiway is not on the NOAA chart (it also is not on the commercial chart) which caused distraction while he tried to determine where he was. He reports that there is a hold short marking but he missed seeing it.

Title: THE HOLD SHORT LINE WAS CROSSED AT DAB, FL ARPT WHILE THE PLT WAS LOOKING AT HIS ARPT DIAGRAM FINDING THE TXWY HE WAS ON WAS NOT DOCUMENTED.

Narrative: MISTAKENLY TAXIED A FEW FEET PAST HOLD SHORT LINE WHILE TRYING TO FIND UNDOCUMENTED TXWY (NOT ON ARPT DIAGRAM). IT WOULD BE HELPFUL IF ARPT DIAGRAM UPDATED TO SHOW EXIT OFF RWY 7L TO SOUTH. AS IS OFTEN THE CASE, DISTRACTION WAS A SIGNIFICANT FACTOR. TO PREVENT RECURRENCE, MUST REMAIN MORE ALERT ESPECIALLY IF NON-GRAPHED TXWYS INTERSECT RWYS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR WAS USING THE GOVERNMENT CHART. HE SAID THAT HE WAS APPROACHING THE RWY 25R FROM THE SOUTH ON A TXWY THAT INTERSECTS THE RWY AT ABOUT THE SAME POINT AS TXWY 5N DOES ON THE NORTH SIDE OF THE RWY. HE ALLEGES THAT THE TXWY IS NOT ON THE NOAA CHART (IT ALSO IS NOT ON THE COMMERCIAL CHART) WHICH CAUSED DISTRACTION WHILE HE TRIED TO DETERMINE WHERE HE WAS. HE REPORTS THAT THERE IS A HOLD SHORT MARKING BUT HE MISSED SEEING IT.
