There have been others.
Numerous sources say that a prop reversal is the cause of the loss of control in this one. I don't know know the total number of accidents due to props entering beta range, but I suspect that it's more then the ones which have been mentioned here. I have a co-worker who was involved in one whcih didn't turn into an accident due to his quick thinking. He was engineer on an checkride, and just as the plane lifted off it started an un-commanded turn that the pilot was unable to control, heading for a hangar. He saw that one of the beta lights was illuminated, and reached up and shut down that engine using the T-handle.
