Today, 5 May 2017, ATSB published a second interim report into the pitch disconnect and serious in-flight damage to an ATR 72 in February 2014.

The horizontal stabilizer was overloaded well beyond design capability and visibly twisted. The weakened aircraft stayed in service for five days until the damage was found almost by chance.
At first read ATSB has done a thorough job and confronted ATR and EASA with design and certification issues as bluntly as it can.
However it should not take ATSB over three years just to reach a second interim report. And ATSB has yet to address local issues that put so many passengers at risk.
