Aldo Sterone provides a detailed debrief of the fatal DR‑400 accident that occurred on 12 October 2023 off the coast of Propriano, Corsica. He reconstructs the day’s timeline: four occupants (pilot, his wife, and another couple) flew from Cannes to Propriano in the morning without incident, then prepared for the return flight in the late afternoon. The pilot struggled to start the Lycoming 360 engine, requiring ten attempts in total (three before refueling, four after refueling, three before take‑off). After a brief three‑minute interval between the final start and take‑off, the aircraft lifted off at about 17:40. Within 40 seconds, black smoke appeared, indicating a loss of power. The plane stalled at low altitude, the pilot pulled back on the control column, causing a rapid loss of airspeed, a stall, and a vertical plunge into the sea, where all four occupants were killed. Sterone cites the BEA’s investigation, which found no mechanical failure in the engine but could not examine the destroyed carburetor, suggesting a probable carburetion issue. He presents BEA statistics on 31 engine‑failure cases: 12 fatal, 14 loss‑of‑control incidents, and a higher fatality rate when a student and instructor are aboard, with pilot experience showing little correlation to outcome. Sterone critiques the pilot’s handling of the emergency, emphasizing that the correct response to an engine‑out over water is to push the stick forward, glide, and attempt a controlled ditching, citing a successful Fokker 27 ditching in Mogadishu as an example. He also discusses operational pressure to depart despite engine issues, and briefly remarks that from an insurer’s perspective the aircraft’s material loss is secondary to the loss of life. The video concludes with thanks to Patreon supporters and a sign‑off.
