Avenger,
First let me say thanks for your reply.
I should have stated this earlier, but I was specifically looking for the FAA's view on this. The question came up as a result of me and some fellow instructors sitting around talking about logging flight time. If an instructor loses his logbook, and there is no way to accurately track his previous flight-time, except the electronic log, what can he do?
will a sign statement from this instructor suffice as a legal record showing hours?
