“The leaking of the CVR data is a serious breach of fundamental and globally accepted international accident investigation rules. The motivation for and consequences of this will need to be addressed,” ECA said.
On Thursday, French prosecutor Brice Robin said the cockpit voice recorder (CVR) analysis revealed that co-pilot Andreas Lubitz was alone in the cockpit at the time of the crash; the flight’s captain was apparently locked out. “While he is alone, the co-pilot presses the buttons of the flight monitoring system to put into action the descent of the airplane,” Robin said, adding, “This action on the altitude controls can only be deliberate.”

The body acknowledged that questions remain unanswered, even though many facts point to one particular theory for the cause of this event. However, it stressed that thorough analysis of technical data from the flight data recorder as part of an unbiased, independent investigation will be “crucial” in verifying what happened.
“Given the level of pressure this leak has undoubtedly created, the investigation team faces a serious distraction. The required lead of safety investigators appears to have been displaced by prosecutorial considerations. This is highly prejudicial, and an impediment to making aviation safer with lessons from the tragedy,” the union said.
