Yes, but a short shaft failure on a B206 that has an engine producing 300 shp one moment, which when suddenly unloaded, makes me wonder of the instantaneous engine acceleration that might occur, and how effective a hydromechanical GP or PT governor might be at limiting any resulting affects from that. I haven't seen a C20 fail before, but I have seen a C30 hand out free samples of expensive engine bits and pieces flung far and wide. It gets very messy very quickly.
