Lost logs, messy logs

05465_LogbooksOne of the worst things that can happen to a pilot is to lose a logbook, especially  a logbook that is fat with hours and experience. It doesn’t matter how it happens, so you need to have a plan.

If you use an electronic logbook and don’t back it up somewhere, you can be in the same bad way. The advantages of electronic logs is that you can back them up more easily; you can save screen shots; and you can copy them to a spreadsheet.

There are a couple of options if you lose a logbook. If you have a copy of your most recent FAA form 8710, you are off to a good start. The FAA will allow you to use the 8710 in lieu of a logbook because you are required to fill in the various flight times for each certificate or rating evaluation. This alone makes it worth using the 8710 to record all of the times that it has blocks for, even if they don’t apply to your particular checkride. Make a copy of it and keep it in a safe place.

Another option to use Excel to produce a duplication of your logbook page. I use the program to do all of the math, and then transfer it to the paper log. I don’t have the desire for an electronic logbook, but this allows me to take away all of the math errors while keeping accurate times for the various airplanes I have flown.

Another logbook issue is that of the messy log. It’s generally frowned upon to have a log that has a lot of white-out, scratches, et cetera, but  most of us have a few pages somewhere with mistakes that needed fixing. If that happens, use a single line to mark out the error, initial, and neatly correct it.

If you have a page with a major snafu, mark the page with an asterisk, then move to the most recent page and use fresh lines to fix the mistake. It will help if you put page numbers on the pages so that you can reference the area where you need to fix a mistake. I ran into this a few years ago when I realized I had made a couple of major math mistakes. Once I sorted it out, I went to the first blank line, made the appropriate notations, and started over on a fresh page. That’s also what drove me to do the Excel plan. Sorry, no e-logs for me!

Logbook entries should be recorded neatly. If you are looking for a job, an interviewer should have no trouble deciphering your writing. Try to use the same color ink, and more important, keep it up to date. As for avoiding issues with losing it, take a picture every couple of pages, especially if something important happens, such as a new rating or certificate. If you use the summary pages in the back—and you should—then take a picture each time you update one of them as well.

Your logbook is much more than a personal diary. It’s a regulatory requirement, and trying to reconstruct it with receipts or memory is hard. Keep it up to date, so that if you do lose it, you can start up from scratch with as little lost as possible.—Chip Wright


  1. So? Where is a reference to mobile logbooks with automatic back up onto the cloud.

    This seems like the way to go to me. Forget paper completely.

    Xcel copies? Sure, but you better have one copy in the cloud. Making copies does nothing if the house burns down and your copies are in the same house.

    Cloud-based logbooks will eventually do away with the paper version. The convenience and safety is too obvious to ignore.

  2. When I finish a page I scan it. Every six months I back up all my computer files.
