If you read the HongKong CAA report you'll find that nowhere do they suggest that the White Tail rotor blade broke on impact with the water .
What it does imply in the report is the TR imbalance might have caused the tail pylon strike which would be in the air and not post water impact.
Also , if one sees the Gulf Helicopter ground incident (2nd one) , it appears that one TR blade has broken away causing similar damage .
That AW had issued ADs to inspect the TR blade for cracks in the past and now again on blades of much lesser hours puts the needle of suspicion on the TR manufacture and quality control !!
AW has to act fast and correctly this time else its really going to hurt both its credibility and its market share !!
