I've seen it a couple of times, but porpoising is much more common.
We had a friend earn his ticket in Iowa City a few years ago who porpoised a
rental Archer so badly that the nosewheel collapsed and the engine had to be
torn down. The prop was a total loss, too, of course.
Sadly, it rattled him so badly that he absolutely disappeared off the face
of the earth after that episode. I've never seen him again, and I presume
he's quit flying.
