FWIW I had an annual in which the mechanics were convinced I had a lightning strike. There were marks on the prop tips and a pair of blackened rivets in the tail. I presume it was a static discharge from flying in dry snow, but regardless the insurance company paid for the teardowns necessary to insure there was no hidden internal damage. The plane is registered in a Corp. and there was no question about a lease or the type of operation.

Up until a few years ago the plane was almost exclusively used for business purposes, but nobody has ever even questioned its use. It is Part 91.
