There was a structural failure on a cliffhanger in new York the immediate fix is that all cliff hangers must have a NDT test( mag particle) before they can operate.
All states are ok with this except north Carolina who is currently fighting with Dartron to keep them banned, even though the failure analysis and engineers say they are safe. Also of the 65 cliff hangers currently traveling about 58 have already had the NDT testing done and only 2 have came back with indications, one of which had been modified not according to manufacturer protocol.
There will be another bulletin coming out in the very near future about another plate that will have to be put in to further strengthen the area in question. The bulletin will require this to be done by the end of te year but not immediately, hopefully this solution makes the state of north Carolina happy and they will be able to operate again.
Darton is also going to release a new part for the bottom part of the seats that will strengthen those plastic pieces and stop the cracking
