It focused on a fuel leak on an Air France flight from Brazzaville in the Republic of Congo to Paris in December 2020, when pilots rerouted the plane but didn't cut power to the engine or land as soon as possible, as leak procedure requires. The plane landed safely in Chad, but the BEA report warned that the engine could have caught fire.
It mentioned three similar cases between 2017 and 2022, and said some pilots are acting based on their own analysis of the situation instead of safety protocols.
Air France said it is carrying out a safety audit in response. It pledged to follow the BEA's recommendations, which include allowing pilots to study their flights afterward and making training manuals stricter about sticking to procedure.
The airline noted that it flies thousands of flights daily and the report mentions only four such safety incidents.
Air France pilots unions have insisted that security is paramount to all pilots and defended pilot actions during emergency situations.
The BEA also investigated an incident in April involving an Air France flight from New York's JFK airport that suffered flight control problems on approach to its landing in Paris.
