The airplane touched down more than halfway beyond the approach end of runway 9; a 3,347-foot-long, 50-foot-wide, asphalt runway. The pilot applied heavy braking, and the airplane veered off the right side of the runway. Examination of the wreckage revealed that the left brake disc had separated from its housing. The right brake disc had cracked, but remained attached to its housing. The left and right brake discs exhibited corrosion. The airplane's most recent annual inspection was completed about 4 months prior to the accident. The mechanic that performed the annual inspection stated that he did not observe corrosion on the brakes at that time. Airworthiness Directive (AD) 71-06-08 addressed repetitive brake disc inspections and replacements; however, the make and model brake disk on the accident airplane was not included on the AD. The reported weather at an airport near the accident site, about the time of the accident, included winds from 160 degrees at 8 knots, varying between 120 degrees and 200 degrees.
Probable Cause: The total failure of the left brake disc due to corrosion.
