The aircraft was repaired and flying again shortly after that incident.
Oooo, I hope that the "shortly" included a replacement fin, fuselage repair, probably some wing repair, an engine and prop inspection. That's quite a lot of work!
Fuel high up in wing tanks also play a role in nose overs like this.
But could it be used as an excuse for the nose over during a landing competition? Or, was the pilot just working the plane too hard?
