I have seen almost identical damage to a C 152. In that case it was a badly botched spin recovery by an instructor who tried to extend the spin to 3 turns but let up on the elevator so that the aircraft entered a spiral dive. By the time the clueless instructor realized what was happening he was going through redline and then damaged the aircraft with an aggressive pull out.
Personally I am godsmacked that so much damage was done on a simple recovery from a miss trim induced dive. Sadly the "solution" isn't to make sure instructors can actually fly airplanes without breaking them, it is to make more rules at the flight school telling them how to teach students how to trim
