## Discrepancy

DURING DISASSEMBLY OF AILERON FOR SKIN CHANGE, THE SPAR WAS FOUND CRACKED IN TWO PLACES AROUND OUTBOARD HINGE BRACKET. THE CRACKS WERE THE FULL WIDTH OF THE SPAR WEB AND INTO THE RADIUS OF THE FLANGES.  THIS IS THE SECOND SPAR FOUND CRACKED LIKE THIS RECENTLY.  SUBMITTER SUGGESTED MANDATORY VISUAL INSPECTION OF THE AILERON SPAR IS STRONGLY RECOMMENDED.
