The captain’s abrupt, last-minute turn to avoid clouds caused a momentary loss of control of a Jetfly Pilatus PC-12 during its descent to France’s Brive-Souillac Airport. According to French aircraft accident investigation agency BEA, the Oct. 12, 2021 “serious incident” involved stall warning activation and an unintentional descent below the minimum safe altitude (MSA) before the aircraft was recovered.
During the descent, the chartered PC-12 encountered intense turbulence after passing through a cloud mass, for which the airborne weather radar was showing weak precipitation. To ensure the comfort of the three passengers, the copilot insisted that the captain (pilot flying) avoid another cloud mass that she could see ahead of them. Relying on his radar, the captain “refused to change the flight path and continued descending to the 3,000-foot MSA for which he had been given clearance.”
