Analysis

During landing roll the left gear collapsed & the acft ground looped. Exam of the left gear strut revealed presence of a preexisting crack. The crack was located inside the gear casting & it was not visible during preflight inspections. The acft reportedly had been used in agricultural operations before being acquired by its present owner.
