This incident is currently the subject of a safety investigation. Since the BEA identified two similar incidents that occurred over a seven-month period, a joint interim report for the three investigations was published on July 23, 2025, and is available in the REPORT tab.

The three safety investigations will focus on the following topics:

• analysis of the DRAIMS failure;
• development and certification of the DRAIMS;
• procedures and training for controllers in abnormal and urgent situations;
• radio failure and/or transponder failure procedures;
• possibility to access primary radar information to manage an aircraft with a transponder
failure;
• coordination with military units for in-flight assistance for aircraft in difficulty or in a distress
situation;
• transmission/reception capabilities of control units on the aeronautical emergency
frequency.
