KEY FINDINGS

WHAT HAPPENDED?

Co-pilot Andreas Lubitz killed 150 people when he deliberately flew flight 9525, flying from Barcelona to Dusseldorf, into a mountain in the French Alps after locking the pilot out of the cockpit on March 24 last year

FLYING ON A MEDICAL CERTIFICATE

Lubitz had been flying on a medical certificate that contained a waiver because of a severe depressive episode from August 2008 to July 2009. The waiver stated that the certificate would become invalid if there was a relapse into depression

FAILED TO IDENTIFY RISKS

The agency found that the certification process failed to identify the risks presented by Lubitz. It said one factor leading to the crash might have been a “lack of clear guidelines in German regulations on when a threat to public safety outweighs” patient privacy

DEPRESSION TENDENCIES

Lubitz had been treated for depression and suicidal tendencies, and documents seized by prosecutors show he partly hid his medical history from employers. He interrupted his Lufthansa training for several months due to psychological problems. He was allowed to return in 2009, having received the “all clear” from his doctors - though his aviation record now contained the note “specific regular examination”

AIRLINES NOT AWARE

Lufthansa said it was aware of Lubitz’s depressive episode, but Germanwings said it had no knowledge of his illness.
