Renton, WA, USA
N8685S
Cessna 150
The flight instructor in the tailwheel-equipped airplane reported that, after landing, the airplane veered left. In an attempt to correct back to centerline, the pilot receiving instruction applied full right rudder. The instructor immediately applied full left rudder and brake to prevent a ground-loop, but the airplane ground looped to the right, the left main landing gear collapsed, and the left wing impacted the ground. The airplane sustained substantial damage to the left wing. The instructor reported that a Federal Aviation Administration inspector examined the airplane's systems and found no anomalies. The airport's automated weather observation station reported that, about the time of the accident, the wind was variable at 3 knots. The pilot landed the airplane on runway 34.
