This one will take 12 months minimum. Possibly up to 18 months.
The bureaucratic pony pooh and layers of Political person(s) the final report has to go through is what generally adds to the timeframe unfortunately.
However, should, and I say should the airline itself be found to blame or be partially to blame for any reason such as cost cutting, lack of/inefficient training, corner cutting, safety issues, or any element of such nature then I hope the accountable mangers/directors are thrown in the big house. That is after all why the laws changed some time back and accountability as well as punitive measures can and should be considered against the accountable persons needs to be upheld.
Then again it could have been just a latent condition/design fault or simple pilot error.
