Is there a single case of a BRS being used on ANY aircraft that the airframe wasn't damaged?

I was just wondering if there is a single case of a helicopter doing an
actual auto rotation were it wasn't damaged. When I flew the Bell 47 it
wasn't much of an issue but the big lifting helos and even the Jet
Rangers don't have it quite so easy. I think the weights they put on
the ends of the rotors are only there to give enough energy to save
lives, not necessarily to avoid damaging the aircraft.
