Yes those statistics look bad, but statistics can be adjusted to suit an individuals leanings. The Puma family has been around for more than 45 years, I first flew them more than 35 years ago.
I don't have them, but if you look at the statistics of Puma family on the NS over this period you will find the ratio of years/accidents very low.
The result is dependent on the time scale short period, not good - long period, very good.
However I do understand where you are coming from, but for those who flew in the Puma before these recent incidents would only be complaining of discomfort.
