Analysis

Upon arriving at an air show the plt was given advisories for a downwind landing. The acft subsequently ground-looped. Subsequent inspection revealed that the tailwheel lock had also malfunctioned. The centering spring was not strong enough to consistently center the tailwheel post so that the lock pin could enter. In addition, the compression spring was too weak to force the lock pin into place.
