PARIS (AP) French air accident investigators are issuing a report about what led to the March 2015 Germanwings jet crash and will give recommendations on how to prevent a repeat scenario.

Investigators say co-pilot Andreas Lubitz intentionally crashed the plane into the French Alps, killing all 150 people on board Flight 9525 from Barcelona to Duesseldorf. Most victims were German and Spanish.

The report Sunday is likely to address cockpit door rules, because Lubitz locked the pilot out of the cockpit thanks to measures introduced to prevent attackers from accessing a plane's controls. It is also expected to recommend tougher reporting requirements for pilots' doctors and urge relaxing medical privacy restrictions in cases of a threat to public safety.

Lubitz saw dozens of doctors in the months before the crash.
