## Discrepancy

THE MAIN SPARS (PN 4500-01 AND 4500-02, RT AND LT) WERE BROKEN AWAY FROM THE WINGLET.  WINGLETS AND SPAR ARE PART OF STC INSTALLATION.  SPAR IS ATTACHED TO INSIDE WINGLET WITH FIBERGLASS CLOTH.  CLOTH WAS TORN AND DELAMINATED.  SPAR WAS COMPLETELY SEPARATED FROM WINGLET ON RT SIDE AND MOSTLY SEPARATED ON THE LT SIDE. DISCOVERED DURING INSPECTION.
