## Discrepancy

DURING 100 HOUR INSPECTION, IT WAS DISCOVERED THAT THE INNER FIBERGLASS SKIN OF THE UPPER AFT SECTION OF THE ENGINE COWLING HAD DISBONDED FROM THE HONEYCOMB STRUCTURE OF THE COWLING. PRYROPEL INSULATION WAS TO BE INSTALLED WHILE THE AIRCRAFT WAS IN INSPECTION AND THE COWLING WAS REMOVED TO FACILITATE THIS MAINTENANCE. REPAIRS TO BE MADE TO COWLING IAW MANUFACTURER'S REPAIR PROCEDURES. THEN PRYROPEL WILL BE INSTALLED IAW SOW-03-087.
