## Discrepancy

DURING LT LEADING EDGE SKIN REPLACEMENT OF HORIZONTAL STABILIZER DUE TO BIRDSTRIKE FOUND BOTH IB LEADING EDGE RIBS PN 0432001-46/ -6 CRACKED THROUGH UPPER AND LOWER MOUNTING TABS. WORKING RIVETS WERE FOUND AT THE TABS AND 2 RIVETS OB ON FORWARD SPAR. BIRDSTRIKE DID NOT CAUSE CRACKS. THESE TABS ARE DIFFICULT TO INSPECT WITHOUT DISASSEMBLY OF TAIL. ANY EVIDENCE OF DEFECTS IN THE TAIL STRUCTURE SHOULD BE INVESTIGATED THOROUGHLY AS THEY ARE PRONE TO CRACKING AND WEAR.
