## Discrepancy

IAW REQUIREMENTS OF FAR 145.63, SUBMITS THIS 8010-4.  IN THE PROCESS OF PERFORMING A PHASE 2 AND 3 INSPECTION, DIAGONAL WRINKLES WERE DISCOVERED ON THE TOP LT WING PANEL BETWEEN THE AUX AND AFT SPARS IB OF THE NACELLE.  AFTER CONTACT WITH AND REVIEW BY MFG ENGINEERING, MFG RECOMMENDED THE WING PANEL BE REPLACED.  MFG STATED NO DIAGONAL WRINKLES WERE ACCEPTABLE IN THE PANEL IN QUESTION AND WAS AN INDICATION OF A HARD LANDING.  MFG MM DOES NOT CALL FOR AN INSPECTION OF THE TOP WING PANEL DURING A HARD LANDING INSPECTION, ONLY THE BOTTOM PANELS.  MFG HAD NO RECOMMENDATION FOR A REPAIR OR A FIX FOR THE PROBLEM ONLY REPLACEMENT OF THE PANEL.
