## Discrepancy

COWLING MOUNT FAILED, SEPARATED BETWEEN QUICK LOCK AND BASE.  THIS ALLOWED COWL TO MOVE AND CONTACT PROPELLER AFT SPINNER FACE.  EVENT OCCURRED UNDER NORMAL FLIGHT CONDITIONS.  PROBABLE CAUSE IS SUBSTANDARD MATERIAL AND/OR PROCESSING DURING PART MFG.  RECOMMEND LOT NR 30-16601 PLATEMOUNT NOT BE USED.
