## Analysis

THE ACFT WENT OFF THE END OF THE RWY DURING AN ABORTED TAKEOFF AFTER THE ENGINE BACKFIRED AND RAN ROUGH. THE PLT CLOSED THE THROTTLE AS HE DISCONTINUED THE TAKEOFF. BEFORE THE ACFT COULD BE STOPPED IT WENT OFF THE RWYS END AND DOWN AN EMBANKMENT. POST ACCIDENT EXAMINATION OF THE SPARK PLUGS SHOWED THEM TO BE WORN AND DIRTY WITH CARBON. THE LAST ANNUAL INSPECTION WAS ON 1/21/83. THIS FLT WAS A DUAL INSTRUCTIONAL FLT TO PREPARE THE PRIVATE PLT FOR AN INSTRUMENT CHECK.
