Landing and Runway Excursion
The airplane landed beyond the halfway point of runway 9, a 3,347-foot-long, 50-foot-wide asphalt runway. The pilot applied heavy braking, which caused the airplane to veer off the right side of the runway.
Brake System Examination
Post-accident examination of the wreckage showed that the left brake disc had separated from its housing. The right brake disc had cracked but remained attached. Both left and right brake discs exhibited corrosion.
Recent Maintenance
The airplane’s most recent annual inspection had been completed approximately four months prior to the accident. The mechanic who performed that inspection stated that he did not observe corrosion on the brakes at that time.
Airworthiness Directive Applicability
Airworthiness Directive (AD) 71-06-08 addresses repetitive brake disc inspections and replacements; however, the make and model of brake disc installed on the accident airplane was not included on the AD.
Weather Conditions
Weather reported at an airport near the accident site around the time of the accident included winds from 160 degrees at 8 knots, varying between 120 degrees and 200 degrees.
