## Discrepancy

(1/2018) BASIC 6 CHECK AT SAL, REPORTED 2 CRACKS ON THE LT WING LOWER SKIN (P/N 190-33065-009, REF /3/) AT THE AFT EDGE BETWEEN RIBS 9-10, AS SHOWN IN THE REF /1/ EA. THE DAMAGE WAS EVALUATED AGAINST THE SRM AND FOUND TO BE OUT OF LIMITS OF THE REF /4/ SRM. THEREFORE CONTACTED FOR REPAIR DISPOSITION. PROVIDED THE REF /2/ ETD WHICH PROVIDES INSTRUCTIONS TO CUT OUT THE CRACKS, PERFORM NDT INSPECTIONS AND INSTALL A REPAIR DOUBLER. THE REF /2/ ETD IS A TIME LIMITED REPAIR REQUIRING A DETAILED STRUCTURAL ANALYSIS WITH 12 MONTHS. THIS EC TRACKS THE 12 MONTH RESTRICTION FOR THE DETAILED STRUCTURAL ANALYSIS. AND COMPLIES WITH REF /2/ ETD WITHOUT DEVIATION; ISSUED REF. /5/ TO ACCOMPLISH THE PERMANENT REPAIR ON THE LT WING LOWER SKIN (P/N 190-33065-009) AT THE AFT EDGE BETWEEN RIBS 9-10. THE PERMANENT REPAIR IS OF SIMILAR TO THE TEMPORARY REPAIR PRINCIPLE WITH THE EXCEPTION OF AN EXTENDED DOUBLER. SEE REF. /5/ FOR DETAILS.
