Aircraft involved
Probable cause & findings
The pilot’s improper landing flare, which resulted in a long landing and a runway excursion.
Factual narrative
The pilot reported that, while enroute, he noticed a loose camlock screw on the engine cowling and decided to land the airplane at the nearest airport. He added that, during the landing, he applied the brakes, but they had "minimal effect". As the airplane slowed "very slightly", he determined he could make the taxiway turn. But, he added that, "the left steering did not effect direction", the airplane exited the runway, and went over the runway embankment. The airplane sustained substantial damage to the left wing. The pilot reported that the brakes failed to slow the airplane to a complete stop, and the nose wheel failed to turn. A local mechanic inspected the brakes following the accident and found no anomalies. The airport manager reported that, marks on the runway showed the airplane touched down approximately 1000 to 1500 ft beyond the approach end of the runway. Additionally, there was approximately a 150 ft. long skid mark showing a skidding left turn before the airplane exited the runway. Pictures submitted by the Federal Aviation Administration inspector showed the skid marks turning left while exiting the end of the runway. The airport supplement states, runway 25 slopes downhill to west.
