I think its a nice and well structured site to be fair. I'm not sure when it was published (the site) but its a great step forward. Fair play to whoever pushed it forward.
Its pretty belt, braces and kitchen sink now and you can't see them having issue with the 225 in the interim period but couple things that seem odd:-
1) what testing and analysis was done around the revised shaft that was fitted to the aircraft in the 1st accident (given it was pretty low time 167hours).
2) what drove the 2000hr TBO and 20000hr life for the 225 shaft.
It just seems odd to have been caught out this way with what look pretty fundamental issues.
