Stop being so defensive. The NTSB report was generated sometimes in 1994 and published in 1995 and it was primarily addressing somewhere around 27 loss of control accidents involving the R-22. In that report comparisons between several helicopter types are made including the H-300 and the comparison was as to the accident rate and not loss of control or rotor incursion or mast separation. It may be true that 5 H-300s have crashed due to a faulty cluster weld assembly but the problem has been addressed and it should not happen again if the weld assembly has been replaced or properly welded.
In one NTSB report on an H-300 crash not related to a cluster weld failure they indicated that there was severe corrosion inside the cluster weld assembly. Maybe this problem should also be addressed.
Since the NTSB report was issued and the SFAR was promulgated there has been two loss of control accidents in the UK, one in Ireland, one in South America and one in the USA for a total of over 31 accidents due to loss of control. Aside from the SFAR there have been flight restrictions placed on the Robinson helicopters and still these accidents continue to occur.
One word comes to mind. Rotorhead.
