When the pilot arrived at the destination, he noted that the wind direction indicator showed apparently calm conditions. Almost immediately after touchdown the aircraft began to swing to the right. Attempts to correct the swing were unsuccessful and the left gear leg collapsed. After vacating the aircraft the pilot noticed that there had been a quartering tailwind of about 10 knots during the landing. The pilot was inexperienced on the operation of tailwheel type aircraft, this being his first flight on such a type following a two hour endorsement. This accident was not the subject of an on-site investigation.
