Voluntary flight interruption and beach landing at Gâvres due to adverse weather (F-GTVY)

Incident Overview and Flight Details On 22 February 2015 at 16:25 local time, a Robin DR400-140B aircraft, registration F-GTVY, operated by a club, made a voluntary landing on the beach at Gâvres (56) in France. The general aviation flight was carrying a pilot and three passengers. The incident resulted in no injuries or damage to the aircraft. ## Flight Progression and Weather Conditions The pilot arrived at Pontivy aerodrome around 11:30 and departed at 12:15 for La Baule-Escoublac (44). During initial climb, the pilot considered returning due to visibility but continued along the Atlantic coast. After a stop, the pilot and passengers returned to the aerodrome around 15:30 for the return flight. At that time, it was raining with visibility of 5 km and a ceiling of 1,500 ft. The pilot contacted a relative in Pontivy for weather information but did not retrieve the most recent available meteorological data. During the return flight, the cloud base progressively lowered, forcing the aircraft down to 500 ft. The pilot contacted the approach controller at Lorient-Lann-Bihoué (56) for radar guidance. The controller, noting the pilot was operating under Visual Flight Rules (VFR), provided a route to the aerodrome's vertical but could not offer full radar guidance. The controller reported special VFR conditions at the field with a 400 ft ceiling and 1,900 m visibility. ## Regulatory Context and Controller Interaction Under the new European regulation (SERA) applicable in France since 4 December 2014, special VFR flights in a Control Zone (CTR) require specific conditions, including a ceiling not lower than 600 ft and ground visibility not less than 1,500 m. The controller informed the pilot that under the new rules, the pilot should not have entered the CTR. The pilot requested emergency landing permission at Lorient-Lann-Bihoué, but the controller initially asked the pilot to hold in 360-degree turns due to conditions below special VFR minima and the lack of prior notice. After consultation, the controller authorized the pilot to land at Lorient-Lann-Bihoué, providing a route 310 to the aerodrome, which was 5 nautical miles away. However, with the aircraft at 100 ft and visibility of 1,500 m, the pilot decided to land on Gâvres beach, facing east, after verifying the beach was clear. The aircraft stopped quickly in the sand without damage, and all four occupants evacuated safely. ## Meteorological Analysis A warm front moving eastward brought stratus clouds and reduced visibility due to drizzle between La Baule and Pontivy around 16:00. Estimated conditions at Gâvres beach were similar to or worse than those at Lorient-Lann-Bihoué, with south winds of 15-20 kt (gusts 25-30 kt), visibility near 2 km or less than 1,500 m, stratus with a base between 300-500 ft (locally below 300 ft), drizzle, and probable fog. Temperature and dew point were both +8°C. ## Findings and Safety Lessons The BEA concluded that the flight interruption and beach landing resulted from insufficient flight preparation by the pilot at La Baule-Escoublac. The failure to review the most recent available weather information prevented the pilot from recognizing the passage of a warm front between the two planned flights. This front was characterized by low ceilings, possible stratus, low visibility, and drizzle. The combination of the following factors prevented the pilot from anticipating an alternative to the beach landing: - The decision to continue flying in deteriorating weather conditions; - The controller's approximate application of special VFR conditions under the new regulation and the lack of explicit phrasing regarding transit through the Lorient-Lann-Bihoué CTR, which led the pilot to continue along the coast and enter the CTR without authorization under conditions that did not permit it; - The pilot's approximate and late declaration, related to the emergency situation caused by the weather, which made it difficult to define the nature of the assistance to be provided.
