What was found
WHILE IN C-CHECK, MAINTENANCE DISCOVERED THAT PREVIOUS REPAIRS TO THE LT AND RT AFT NOSE GEAR DOOR HINGE CUTOUTS WERE CRACKING. PREVIOUSLY, THE SRM AUTHORIZED A REPAIR USING A 0.050 THICK DOUBLER TO REPAIR 0.063" SKIN; THIS REPAIR HAS SINCE BEEN SUPERSEDED BECAUSE IT WAS FOUND TO CRACK AND FAIL.

HOWEVER THERE IS A FASTENER COUNT MISMATCH BETWEEN THE OLD AND NEW SRM REPAIRS. ER/A 545552-14 AUTHORIZES THE CONTINUED INSTALLATION OF THE DOUBLER WITH THE OLD SRM REPAIR FASTENER COUNT. COMPLIED WITH ER/A 545552-14, REV, ORIGINAL, ASSOCIATED ER/A 14-545552, ADDED FOR AC 9007.
