I recently discovered an addition error I made in my logbook a few years back. In the grand scheme of things the error is not significant, correcting it would add 10 hour to my PIC total. Is it best to go back, correct the error (and have white out on each of the following 60 pages or so), or should I add the hours to my current total, along with an explaination in my logbook. A third option would be to just forget about it, since the error is relatively insignificant. Any suggestions would be appreciated.
