Here's an intersting subject. I came across this Dauphin 2 at the only aviation museum in Iceland, At first glance, all appears normal. Then I noticed the tail fan. The blades are all sheared off at the base! The documentation says this was due to a training accident and that the helo did not actually crash. I guess whatever it was happened on the ground. You can see indications of stress on the tail. I am guessing it was enough to put it beyond economic repair and it was retired to the museum.
