French investigators on Sunday presented their final report on the Germanwings plane crash where its co-pilot Andreas Lubitz crashed the jet into the French Alps last March, killing all 150 people on board. The report, released nearly a year after the crash, recommended more stringent medical checks for pilots. It also observed that doctors had recommended psychiatric treatment for Lubitz two weeks before he barricaded himself into the cockpit and deliberately propelled the Airbus jet into a mountainside.

The Bureau d'enquêtes et d'analyses, or BEA, report said the German co-pilot had a history of severe depression and had consulted dozens of doctors in the weeks leading to the crash. The 27-year-old had partly hid his medical history from his employers. However, none of the doctors alerted aviation authorities or the pilot's employer about his medical health, the report said. The investigators recommended new rules that bind medical workers to warn authorities when a pilot's mental health could threaten public safety. The BEA also suggested setting up a peer support group for the mental well-being of pilots.
