## Analysis

THE ACFT RAN OFF THE SIDE OF THE RUNWAY AND CONTINUED TO OVERRUN THE DEPARTURE END OF THE RUNWAY WHERE COLLISION WITH A DITCH OCCURRED. THERE WAS EVIDENCE THAT THE BRAKES WERE USED BUT WERE NOT EFFECTIVE IN STOPPING THE ACFT. AN FAA INSPECTOR INSPECTED THE WRECKAGE AT THE SITE AND REPORTED- 'THAT THE ACFT ROLLED 825 FT WITH THE RIGHT WHEEL OFF THE RUNWAY.' HE ALSO REPORTED BOTH BRAKES WORN OUT. THE BRAKE RESERVOIR WAS EMPTY. THE RIGHT BRAKE HELD SOME PRESSURE. THE LEFT BRAKE WOULD HOLD NO PRESSURE. THE LOGBOOKS INDICATED THAT THE LAST ANNUAL INSPECTION WAS PERFORMED ON DEC. 11, 1981. THERE WERE NO INDICATIONS THAT THE BRAKES WERE EXAMINED SINCE THAT LAST ANNUAL.
