Incident Overview
A private pilot reported an incident during the landing roll of a tailwheel airplane on a hard-surfaced runway with an approximate 9-knot tailwind. During the landing roll, the airplane swerved. The pilot attempted to correct the swerve using rudder and brake inputs but was unable to regain control.
Emergency Power Application
In an effort to regain control, the pilot attempted to rapidly apply engine power. However, the engine hesitated before responding. The airplane then ground looped to the right, causing the left wing to strike the runway.
Damage Assessment
During the ground loop, the left aileron sustained substantial damage. The pilot stated that there were no preaccident mechanical problems with the airplane.
Contributing Factors
The source does not explicitly state causal factors. The pilot's report notes the tailwind, the inability to correct the swerve with rudder and brakes, and the engine hesitation during rapid throttle application.
