Narrative:
A Cessna 208B, N942AC, operating as Air Choice One flight 2627, was substantially damaged by high wind during taxi at Chicago O'Hare International Airport (ORD), Chicago, Illinois. The two flight crewmembers and five passengers were not injured and two passengers sustained minor injuries.
The captain reported that there had been numerous reports of windshear and microburst alerts and the airplane had been stationary while waiting for departure clearance. As the airplane began to taxi high wind lifted the airplane and it impacted the concrete taxiway surface on the left wing, left main gear, and the operating propeller. Witnesses reported that after impact the airplane remained partially nose down and resting on its left wing for several seconds. The airplane then fell back upright to come to rest on all three landing gear. The engine was secured, and all occupants deplaned normally through the main cabin door. A postaccident examination showed the outboard portion of the left wing was bent up about 30 degrees, the aileron was damaged, and all three propeller blades were impact damaged.
PROBABLE CAUSE: "An encounter with a wind gust during ground maneuvering and the captain's improper flight control positioning to account for wind conditions, which resulted in the airplane being blown onto its left wing."
