“ you can hear low and high-intensity alarm signals and repeated beating against the door with demands to come into the cockpit,” a Mozambican Civil Aviation Institute official said after the jet’s cockpit voice recorder was retrieved - but the person banging on the cockpit door could not get inside.Īir New Zealand Flight 176 (May 21, 2014) Investigators believe the captain had a “clear intention” to crash the jet. The Embraer 190 crashed in Namibia en route to Angola after descending rapidly from an altitude of 38,000 ft., killing all 33 passengers and crew. (It is not known how the flight attendant obtained the code.) The Guardian reported in 2006 that on this flight, only the senior steward had been permitted to know the code, raising questions of whether open doors - or less protected doors - would have allowed the flight attendant to reach the cockpit sooner. Moments before the plane exhausted its fuel, a flight attendant had managed to enter the locked cockpit using an emergency code and attempted unsuccessfully to control the plane. The Boeing 737 crashed in the mountains near Athens, killing all 121 on board, after the co-pilots became incapacitated after they mistook an in-flight depressurization - which deprives the plane of oxygen - for an air-conditioning malfunction. (Investigators have not said whether the emergency codes were used on the Germanwings plane, though the flight data recorder presumably will provide this information.) The code unlocks the cockpit door within 30 seconds unless someone inside hits the “lock” toggle, in which case there is no way to gain entrance. As a result, many planes - including the Germanwings jet - now have emergency codes to enter the cockpit, which are known only by the flight crew, according to an Airbus manual. For decades, aviation officials have struggled with the paradox of a cockpit that is both secure, in the event of a threat from outside, and accessible, in the event of a threat from within. ![]() The discovery has heightened concerns about whether locked cockpit doors - fortified and enforced in the wake of 9/11 - are more dangerous than they are safe. Prosecutors claiming the crash of Germanwings Flight 9525 was deliberate revealed on Thursday a chilling piece of evidence.Ĭo-pilot Andreas Lubitz, 27, whom investigators believe locked the captain out of the cockpit before putting the plane into a fatal descent, had researched the doors’ security on his iPad before the March 24 crash, investigators said.
