## Discrepancy

LEFT ENG FAILED AFTER TAKEOFF.  UPON INSPECTION, IT WAS NOTED THE NR 5 CYLINDER CONNECTING ROD SEPARATED FROM THE CRANKSHAFT, CAUSING PENETRATION THROUGH THE CASE, EJECTING BOTH MAGNETOS FROM THEIR MOUNTS & CAUSING EXTENSIVE DAMAGE TO THE CYLINDER, CASE & ENG COWLING.  THE MAGNETOS REMAINED TETHERED TO THE ENG BY THE LEAD HARNESSES & DEBRIS WAS CONTAINED WITHIN THE ENG COWLING.  WE DO NOT BELIEVE ANY COMPONENTS OR MATERIAL SEPARATED FROM THE ACFT.  R & R ENG & COWLING.  ENG HAS BEEN SENT OUT FOR TEAR DOWN ANALYSIS.  FURTHER DETERMINATION TO BE REACHED UPON TEAR DOWN ANALYSIS.
