## Discrepancy

DURING AN EVENT 1 INSPECTION, CRACKS IN THE WING SKIN IN THE AREA OF THE LEFT AND RIGHT LOWER WING BOLT FITTING WERE FOUND.  THESE CRACKS TEND TO GO THROUGH THE HOLES WHERE SCREWS ARE USED TO SECURE THE SKIN TO THE WING SPAR CAP, AND EXTEND TO THE HOLE IN THE SKIN FOR THE FUEL DRAIN.  SUBMITTER STATED SEVERAL OF THE E-90 FLEET  HAVE HAD DOUBLERS INSTALLED TO REPAIR THIS PROBLEM IN THE PAST.
