I believe that statement was made because at that point they had confirmed that at bare min that it was not an issue with the bevel gear .... hence not a repeat of anything that had ever happened to the 225 before. Arguably a very bold move not to suspend flights at the time due to the fact that they did not know what happened but really, that's aviation. We do not ground every 206 in the world every time one goes missing in the mountains. Likewise, the fix wing world does not ground the type worldwide if an aircraft crashes ..... at least not until a definitive reason is determined or a pattern has established.
Obviously just my opinion and I have been back and forth with whether I believe airbus handled the situation suitably however, hine sight is 20 20.
