A doctor referred Germanwings co-pilot Andreas Lubitz to a psychiatric clinic two weeks before he crashed a plane into the French Alps, killing 150 people, French air accident investigators have revealed.

The BEA investigation agency, releasing a report on the March 2015 crash, said multiple doctors who treated Lubitz in the weeks before the crash did not inform authorities of concerns about his mental health.

Because Lubitz did not inform anyone of his doctors' warnings, the BEA said "no action could have been taken by the authorities or his employer to prevent him from flying".

Investigators found that Lubitz intentionally crashed Flight 9525 en route from Barcelona to Duesseldorf.

The BEA investigation is separate from a manslaughter investigation by French prosecutors seeking to determine eventual criminal responsibility for the crash.

Investigators are recommending that world aviation bodies define new rules to require that medical professionals warn authorities when a pilot's mental health could threaten public safety.

They made several recommendations to avoid such accidents in the future, notably about pilot mental health and screening before a pilot is certified.

Lubitz had been treated for depression in the past, and the investigation found that he had consulted dozens of doctors in the weeks before the crash.
