Analysis

The commercial plt said that while rolling out, during takeoff and ldgs practice, he heard a popping noise. The right wing began to drop, so a go-around was executed. After several attempts to land, thinking the cross wind was causing the problem, he landed. After about 150 feet into the rollout, the aircraft ground looped to the right. Post accident investigation revealed the weld on the right landing gear strut had failed.
