The pilot said he was too high on his landing approach, the airplane touched down further down the runway than he had planned, and he was not able to stop the airplane prior to it hitting the cinder block wall at the end of the runway. He reported that the winds were light and variable. The pilot further stated that there were no mechanical anomalies with the airplane. The length of the accident runway is 3,322 feet. The NTSB investigator-in-charge observed skid marks that started at 189 yards from the wall and that changed to continuous skid marks 117 yards from the wall.
