According to the pilot, during approach, his altitude was too high on final. He reported that he decided to land and that the landing flare lasted longer than he expected. The airplane touched down beyond mid-field and bounced twice. The pilot reported that as he approached the end of the runway, he attempted a right turn in order to turn off of the runway and on to the taxiway; however his speed was too fast to complete the turn. The airplane exited the runway turn off and traveled down an embankment where it nosed over just short of the highway. The airplane sustained substantial damage to the both wings, fuselage, the rudder and vertical stabilizer. The pilot reported that there were no mechanical failures or anomalies with the airplane prior to or during the flight that would have prevented normal flight operation.
