On December 20, 2002, at 1515 central standard time, a Cessna 195, single-engine airplane, N195SR, departed the runway during the landing roll following a collapse of the right main landing gear at the Winkler County Airport, near Wink, Texas. The airplane was owned and operated by a private individual under 14 Code of Federal Regulations Part 91. The airline transport pilot, the airplane owner, and another passenger were not injured, and the airplane sustained substantial damage. Visual meteorological conditions prevailed for the cross-country flight, and a flight plan was not filed. The flight originated from Fort Worth, Texas, approximately 1200, with a planned destination of El Paso, Texas. The FAA inspector, who responded to the accident site, found the outboard portion of the right wing bent upward with the right main wing spar collapsed. Structural damage was also found at the engine firewall. The right main axle bolt, part number AN10-46A, that attached the landing gear axle to the right main landing gear assembly was found separated from the axle. According to the FAA inspector, the bolt exhibited physical evidence of stripped threads, and the bolt hole at the landing gear axle did not exhibit deformation. Available maintenance records reviewed by the FAA inspector and the NTSB investigator-in-charge did not reveal the maintenance history for the bolt or the landing gear.
