Accident Details
A tail wheel equipped airplane experienced a ground loop upon landing. The event occurred at an airport where the Automated Weather Observation System (AWOS) reported wind from 170 degrees at 4 knots. The pilot entered the traffic pattern at a 45-degree angle to the right downwind for runway 17. During final approach, the pilot reported being unable to see the windsock, but the airplane's stability corresponded with the AWOS data. A three-point full stall landing was executed.
Pilot's Account
Immediately after touchdown, the airplane's tail swung to the left. The pilot applied full left rudder to regain directional control, but the airplane did not respond. The airplane then turned 90 degrees to the right, skidded on the left main landing gear, and tilted to the left. The left wing and horizontal tail surfaces contacted the runway surface, and the airplane came to rest after completing a 180-degree turn. The pilot stated that the airplane and engine had no mechanical failures or malfunctions during the flight.
Wind Conditions
The midfield windsock indicated a 90-degree right crosswind at approximately 10 knots, differing from the AWOS reading. The Airport/Facility Directory (A/FD) entry for Columbia Airport notes that "varying wind direction and velocity may be encountered at midpoint of runway 17-35 due to terrain features and wind flow patterns."
