Accident to the Diamond DA40 registered F-GUVU on 03/04/2023 at Annecy

After engine start-up, a bag that the student-pilot had left on the left wing fell off, probably as a result of the propeller blast. The controller warned the instructor and the student-pilot. In this unusual situation, the instructor decided to leave the engine running and asked the student-pilot to get out to retrieve the bag. The instructor, convinced that the student-pilot was going to exit from the rear, did not think about talking with him to make sure they shared the same strategy. The student-pilot got out from the aeroplane as he was used to doing, from the front, while at the same time looking for his bag, without identifying the risk associated with the rotating propeller. He bent down and moved away from the leading edge to have a better view underneath the wing of the aeroplane. This movement brought him closer to the rotating propeller, which hit him on the right arm
