On September 15, 1999, about 1200 mountain daylight time, a Stinson 108-2, N9358K, registered to and operated by the pilot as a 14 CFR Part 91 personal/pleasure flight, was substantially damaged during the landing roll at Burley Municipal Airport, Burley, Idaho. Visual meteorological conditions prevailed, and no flight plan was filed for the cross country flight. The private pilot and pilot rated passenger were not injured. The flight originated from Sweet Water County Airport, Rock Springs, Wyoming, approximately two hours and 30 minutes prior to the accident. There was no fire and no report of ELT activation. The pilot reported that he made an approach and landing to runway 20, which measures 4,094 feet long by 80 feet wide, with an asphalt surface. According to the pilot, during the landing roll, he applied light braking to slow for an upcoming taxiway. While braking, the aircraft drifted left of the runway centerline. The pilot then applied right rudder and right brake, which according to him, was ineffective. The aircraft veered off the runway and collided with a taxiway marker, resulting in the collapse of the left main gear and substantial damage to the fuselage. A certified Airframe & Powerplant mechanic stated that he inspected the aircraft's braking system, and no evidence was found of a malfunction or failure. At 1152 MDT, Burley weather reported winds from 100 degrees at four knots.
