Lynx,

Some have said, on here, that the Puma family has run up 9 million hours over all marks.
In that time it has had 3 visualy similar (tho not causal) MRH failures where we can ALL graphically imagine the results.

My questions are;

1 At what point does the statistical likelyhood of this event occuring 3 times stop being chance and become an inherant weakness ?- for whatever reason.

2 Does any other type (same operating area/same hours) have similar record of such a failure?
The S61 had at least 3 aircraft chuck a blade back in the late 60s to early 70s. All resulting in a crash, fatally injuring everyone on board. Not the exact failure (rotor head detaching) but same end result. Not sure how familiar you are with aircraft but the S61, prior to the S92 was the Super Pumas main competition. So that happened back then (3 very similar events) and when did we retire the S61? Some 35 years later, as the workhorse of the offshore industry. Most would love to jump back onboard one tomorrow. Mind you, we could not fear monger on Facebook and other forums back then. In fact, the public had to wait until the accident boards revealed the true facts via a live broadcast or new article. Nowadays, the 225 was doomed by the public before the preliminary report was even issued. Thankfully this won't come down to what the public think! The AAIB will complete their investigation and we will carry on from there. Maybe it flies again, maybe not!

Also note, the 3 blade chuckings, were all S61s ... Not a variant of.
