Narrative:

Performed a normal three point landing. While taxiing clear of the runway I performed south turn to the right for forward visibility. The left landing gear collapsed followed by the right gear. Examination of the plane showed the front left gear mounting bracket had separated from the fuselage due to a weld of poor quality with little penetration. The gear failure resulted in the wing scraping the pavement and the prop striking the pavement.
