Aircraft involved

Probable cause & findings

The pilot's improper approach and delayed decision to apply corrective action, which resulted in a runway overrun, impact with a berm, and a subsequent nose-over.

Factual narrative

The pilot reported that during the approach, he was a little high and a little fast and touched down about one quarter of the way down the runway. During the landing roll, the pilot thought that he had reduced the power to idle. However, as he was looking down the runway to see the end, he realized that he was carrying too much power, which would prevent him from stopping in the available runway remaining; it was also too late to initiate a takeoff. He therefore applied maximum braking but was unable to stop the airplane before reaching the end of the runway. Subsequently, the airplane exited the runway, nosed over, and impacted terrain. The airplane sustained substantial damage to the vertical stabilizer and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported that, during the approach, the airplane was a little high and fast and that it touched down about one quarter of the way down the runway. During the landing roll, the pilot thought that he had reduced the power to idle. However, as he was looking down the runway to see the end, he realized that the airplane "was carrying too much" power, that brake application would not be able to stop the airplane in the remaining runway, and that it was too late to go around. He applied maximum braking but was unable to stop the airplane, and it subsequently exited the runway, hit a berm, and nosed over. The airplane sustained substantial damage to the vertical stabilizer and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
