NTSB Narrative Summary Released at Completion of Accident

THE HELICOPTER PLT HAD JUST DISCHARGED HIS PASSENGERS FOLLOWING A FLT FROM AN OFF-SHORE BARGE TO A BEACH HELIPORT. WHEN HE LIFTED OFF & STARTED TO CROSS OVER A FENCE, THE ENG LOST PARTIAL POWER. THE PLT TRIED TO AVOID THE OBSTRUCTION, BUT THE TAIL BOOM HIT THE FENCE & FAILED. THE ACFT THEN HIT THE GROUND & ROLLED OVER. AN ENG TEARDOWN REVEALED THAT THE COMPRESSOR MOUNT ASSEMBLY, P/N 6898611, HAD FAILED FROM FATIGUE AT 3 PAD POSITIONS. THERE WAS EVIDENCE THAT THE COMPRESSOR SPLINE ADAPTER THEN FAILED DUE TO MISALIGNMENT. A REVIEW OF THE MAINTENANCE RECORDS SHOWED THAT A MANDATORY INSPECTION OF THE COMPRESSOR MOUNTS WAS OVERDUE.
