What's your take on the tax perspective? It would seem that the
context of donating something would imply that there is a value
associated with it. If the FAA doesn't care or seem to consider it an
act of charter or "for hire" operation, then it wouldn't be an FAA
concern at that point anymore and would be equivalent to donating
somthing like lawn maintenance services for a day, which would also
have a value attached to it???

I would do it whether there was a tax advantage or not, but it would be
great knowing that it is a completely legitimate write-off.

Best Regards,
