Analysis
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.
