Piper PA28 crash in the Luberon massif, France (F-GFLZ)

Accident Overview and Flight Details On 6 December 2015, a Piper PA28 registered F-GFLZ, operated by a flight school, crashed into the Luberon massif near Peypin d’Aigues (84), France. The aircraft was destroyed, and the sole occupant, the pilot, was killed. The flight was a personal leisure flight from Aix les Milles (13) to Vinon (83), located 20 nautical miles to the northeast. The pilot departed around 10:30 local time. ## Sequence of Events Shortly after takeoff, the pilot contacted Marseille Info and requested permission to climb to 2,800 feet due to fog on the route. The flight information service agent indicated that the regulated zones around Salon were clear and that the pilot could climb as desired. The pilot mentioned possibly climbing to 3,500 feet. Around 10:39, the pilot changed course to the north. At 10:41, at an altitude of 4,550 feet, the pilot reported making a turn back because he could see nothing above, below 4,000 or 5,000 feet. The agent checked the return route to Aix les Milles. The pilot turned back, then turned right toward the west. Two minutes later, he turned right again. The aircraft performed 360-degree turns while losing altitude before striking trees and then the ground on the Luberon massif. ## Meteorological Conditions The estimated weather conditions at the accident site included a wind from 080 degrees at 3 knots, visibility of a few dozen meters, terrain obscured by cloud, light rain, a temperature of 7°C, a dew point of 7°C, and a QNH of 1034. At the time of takeoff, the sky was clear south of Aix les Milles, with the ceiling rising due to diurnal evolution. Further north, the cloud cover remained compact with locally higher tops. The pilot spent the first ten minutes of flight below the main cloud layer, estimated at around 3,500 feet. He then flew alongside a dense, weakly active cloud mass on his right. After turning back, he followed a gap toward the west and then faced another dense cloud line with an estimated minimum top of 7,500 feet. ## Technical and Pilot Information The wreckage was found at an altitude of approximately 2,600 feet. The site and wreckage examination showed that the aircraft struck trees and then the ground with high energy while in a steep right bank. Technical examinations did not reveal any malfunction that could have contributed to the accident. The observed damage was consistent with the engine delivering power at the time of impact. The pilot held a private pilot license (PPL(A)) since 2009, with 342 total flight hours and seven hours in the preceding three months, including one hour on type. He did not hold an instrument rating. No flight preparation documents were found on board, and the pilot had not prepared the flight at the flight school before departure. ## Investigation Findings The accident was probably due to insufficient consideration of weather conditions during flight preparation and late consideration of them in flight. The pilot departed and flew the first ten minutes in visual flight conditions below the cloud layer. He then encountered deteriorating weather, which led him to alter his course and turn back to attempt to return to the departure aerodrome. In doing so, he probably entered the cloud layer. There, lacking sufficient external visual references, the pilot may have suffered spatial disorientation and failed to maintain control of the aircraft.
