Incident
A pilot reported difficulties during approach to his destination, stating he was unable to contact the airport or other air traffic to obtain wind information to determine which runway was in use. After overflying the airport, he observed the wind sock, which indicated calm winds, and subsequently landed on runway 13.
During the landing roll, the pilot noted the airplane 'felt soft on the left side' and began 'weaving' down the runway. The left wheel then broke off the landing gear, and the airplane ground looped.
Witness and Examination
A witness later spoke with the pilot and suggested he 'may have experienced a right quartering tail wind gust.' An FAA inspector who examined the airplane stated that the failure appeared to be overload.
Probable Cause
The FAA inspector determined that the wheel failure was due to overload.
