Event Details
During a local area flight in a tailwheel-equipped airplane, the pilot reported that the approach and landing were uneventful. As the airplane touched down, a herd of antelope entered the left side of the runway and crossed in front of the aircraft. In an attempt to avoid a collision, the pilot steered to the right. The maneuver caused the airplane to ground-loop, which resulted in significant structural damage.
Damage
The airplane's left wing was substantially damaged during the ground loop. The pilot stated that no mechanical failures or malfunctions occurred with either the airframe or the engine prior to the accident.
Pilot Report
The pilot indicated that the landing was proceeding normally until the antelope appeared unexpectedly. The decision to swerve was made to avoid striking the animals. Despite the avoidance maneuver, the aircraft's ground loop led to the damage. The pilot confirmed that all systems were functioning correctly, and there were no preexisting issues with the aircraft.
