## Discrepancy

(CAN) NOSE COWLING PARTIALLY SEPARATED FROM ENGINE CAUSING THE TOP AND RT SEGMENTS OF COWL TO CONTACT THE PROP. AFTER LANDING THE COWL RING WAS INSPECTED AND 5 OF THE 9 ATTACH LUGS HAD FAILED AND 2 OF THE LUGS HAD THE VIBRATION ISOLATORS PULLED THROUGH. THE FAILURE OF THE LUGS WAS PROGRESSIVE IN NATURE AND SHOULD HAVE BEEN VISABLE DURING DAILY AND ROUTINE INSPECTIONS.
