## Discrepancy

DURING SIDE PULL OPERATIONS,  THE SIDE PULL HOOK SHAFT ASSEMBLY SHEARED IN HALF AND DEPARTED THE AIRCRAFT. VISUAL INSPECTIONS INDICATE METALLURGY ISSUES IN THE APPARENT MATERIAL. THE HOOK HAS BEEN SENT OUT FOR FURTHER DAMAGE EVALUATION TO DETERMINE CAUSE OF FAILURE. AT THIS TIME, IT IS BELIEVED TO BE AN ISSUE WITH THE METAL COMPOSITION AS INDICATED BY VISUAL MEANS ALONG WITH OTHER OPERATOR REPORTS.
