DURING HEAVY MAINTENANCE,  REPORTED A 2 CRACKS ON THE RH WING REAR LOWER SKIN (P/N 190-33065-006) BETWEEN RIBS 10-11, AS SHOWN IN THE REF /1/ EA. THE DAMAGE WAS EVALUATED AGAINST THE SRM AND FOUND TO BE OUT OF LIMITS OF THE REF /3/ SRM.   THEREFORE AEROMAN CONTACTED EMBRAER FOR REPAIR DISPOSITION. MANUFACTURER PROVIDED THE REF /2/ ETD WHICH PROVIDES INSTRUCTIONS TO CUT OUT THE CRACK AND OVERSIZE THE CRACKED HOLE TILL CRACK INDICATION DISAPPEARS, 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 PROVIDES THE TIME LIMITED REPAIR INSTRUCTIONS AND COMPLIES WITH REF /2/ ETD WITHOUT DEVIATION. THIS EC E19-359-01 PROVIDES THE PERMANENT REPAIR INSTRUCTIONS PER THE REF /2/ ETD. EC E19-359-02 PROVIDES A PLACEHOLDER TO TRACK THE FOLLOW UP ANALYSIS REQUIRED WITHIN 12 MONTHS; THIS TIME LIMITED REPAIR, REQUIRING FURTHER ANALYSIS WITHIN 12 MONTHS, HAS BEEN APPROVED VIA REF /2/ETD AND IS CLASSIFIED AS MAJOR.
