Despite what others have posted, this is a very common requirement and
insurance companies always grant it. It is not, however, in your best
interest, since it dilutes your insurance coverage.

My concern is the FBO could make a claim without anything actually
happening. I.E. blame me for something I didn't do. While I know the
insurance company should investigate this they may not. It seems in
most instances like this if my plane damaged something the FBO's
insurance would cover this and then their insurance company would go
after my insurance for the claim. Typical scenario is an aircraft
renter damages an airplane. I don't like what appears to be the easy
ability to make a claim against my policy from a third party.

Thanks for the comments so far.
