Lynn - I had already downloaded and searched IRS Publication 526. Lots of useful information there, but nothing specific about use of private aircraft on charitable flights for organizations such as Angel Flight or Pilots N Paws.
unctiatc - Can you please post a pdf of the "letter sent from the FAA and IRS" referenced in your 2/22/2020 post on this topic? I'm sure that would be helpful/useful for many of us who fly charity missions. Also, do you have a separate cash account set up for "engine reserve" or is it simply calculated based on an assumed cost for engine(s) replacement, overhaul or remanufacture?
Thanks,
JD
