## Discrepancy

WHILE COMPLYING WITH THE MAGNETIC PARTICLE INSPECTION OF THE WING ATTACH BOLTS THE RT FORWARD UPPER BOLT WAS FOUND TO BE CRACKED. THE CRACK WAS FOUND ON THE SHANK JUST BELOW THE THREADS OF THE RETAINING (NON LOAD BEARING) SECTION OF THE SPECIAL BOLT. THE CRACK IS PARALLEL WITH THE THREADS AND RUNS FOR APPROXIMATELY 1/4 THE SHANKS CIRCUMFERENCE. THE BOLT WAS REJECTED AND REPLACED.
