## Discrepancy

THE 27-35008-010 KEELSON CAP WAS DISCOVERED CRACKED ON LR RADIUS.  THIS IS A FAIRLY COMMON DEFECT AND WHEN NACELE SKIN WAS REMOVED TO REPLACE IT,  27-35004-002 CAP WAS FOUND CRACKED AS WELL.  THIS PART CAN BE INSPECTED IN SERVICE BUT WOULD BE DIFFICULT TO SEE, IT WAS ONLY AFTER SKIN WAS REMOVED AND THE STRUCTURE CLEANED THAT CRACK WAS EVIDENT.
