Location: Renton, WA
Accident Number: GAA19CA313
Date & Time: 06/04/2019, 1500 PDT
Registration: N8685S
Aircraft: Cessna 150
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Instructional 

Analysis 

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. 

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot receiving instruction failure to maintain directional control and his overapplication of right rudder and the flight instructor's delayed remedial action during the landing, which resulted in a ground-loop.
