As I pulled out of a loop in a Robin 2112 with a friend, there was a loud BANG! Frightened the bejesus out of me! We flew home very sedately wondering what might have broken. When I walked around after the flight I touched the rudder strake which "popped" back (the metal had panted) The bang may not have been more than a pop in reality, but it sure sounded like a BANG at the time!
