Accident Sequence
During an approach to runway 5, the airplane touched down at a speed of 85 knots. Immediately after touchdown, the airplane began to yaw to the right. It subsequently departed the runway surface. The right main landing gear collapsed, and the airplane nosed over.
Examination Findings
Post-accident examination revealed that the right main wheel brake had locked up, and the landing gear had collapsed. The right main landing gear assembly and all associated components were inspected, but no determination could be made as to what caused the brake to lock. The brake assembly was disassembled and each component part was examined. No evidence of malfunction was detected, and no contamination of the hydraulic fluid was found.
Probable Cause
The right main brake locked after touchdown, causing the airplane to yaw and depart the runway, resulting in the landing gear collapsing.
