Analysis

The student pilot departed from his farm field in his 1940, wooden snow-ski equipped airplane. His destination was a frozen lake to practice take-offs and landings. He completed one touch and go landing to check the snow depth. During his second landing to a full stop the left gear collapsed and the airplane slid for about 40 feet in the deep snow covered ice. Examination of the airplane revealed that a weld at the base of the left landing gear failed.

Factual narrative
