## Discrepancy

FOUND CRACKS IN THE WING SKIN ON THE LT WING UPPER CENTER SECTION WHERE IT IS RIVETED TO THE ATTACH FITTING.  THE FORWARD OB FAIRING NEXT TO THE NACELLE MUST BE LIFTED TO SEE THE CRACKS.  LIKELY CAUSED BY LANDING CYCLES AND FATIGUE.  SUBMITTER ADVISES THAT MFG HAS A FIX FOR THIS PROBLEM.
