Cause of Accident
The accident occurred due to loss of control resulting from probable failure of Hydraulic Drag Dampers in flight which imposed excessive loads on the Blade Spacing System resulting in the failure of bolts/links. The severed spacingcable impacted and broke the pitch control rods, leading to loss of control of Helicopter.
Lack of oversight of Maintenance Activities of the AMOs was the contributory factor.
