He retarded the throttle and applied the brakes, and became concerned that the airplane would not be able to stop in time. He decided to initiate a turn onto the taxiway rather than allow the airplane to pass beyond the runway end and down a steep hill. The pilot was unable to complete the turn and the left wing and firewall were substantially damaged when the airplane struck a fence. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation. ## Factual narrative The pilot reported that the approach and landing were normal; however, during the landing roll as the airplane reached about 2/3 of the way down the runway, he realized he was travelling too fast.
