## Discrepancy

THE BLADE WAS REMOVED FROM THE AIRCRAFT FOR BIM INDICATION.  A 10-DAY LEAK CHECK WAS PERFORMED AND A LEAK WAS FOUND IN A CRACK IN NR 18 POCKET.  AFTER THE POCKET WAS REMOVED AND ADHESIVE WAS CHEMICALLY REMOVED, THE CRACK WAS FOUND 168.75 INCHES FROM THE ROOT END AND 9.50 INCHES FROM THE LEADING EDGE ON THE BOTTOM SIDE OF THE BLADE.  THE CRACK IS APPROXIMATELY 3 INCHES LONG AND WRAPS AROUND THE TRAILING EDGE RADIUS TO THE BACK WALL OF THE SPAR.  CAUSE: UNKNOWN
