What was found
DURING A DETAILED INSPECTION OF THE EMPENAGE, THE RT HORIZONTAL STABILIZER HINGE BRACKET P/N 0712042-2 WAS FOUND CRACKED AND HAD (2) SHEARED RIVETS. UPON DISASSEMBLY THE LT BRACKET P/N 0712042-1 WAS FOUND TO HAVE (2) SHEARED RIVETS. THESE PARTS ARE IN THE MFG 180/185 IPC FIG 32 INDEX NR 36 AND NR 37.THERE IS NOTHING IN THE RECORDS THAT SHOW THESE PARTS CHANGED, HOWEVER THE RT BRACKET DID HAVE (2) NR 5 RIVETS WHERE ALL OF THE REST ON BOTH BRACKETS WERE NR 4S. LEADING US TO BELIEVE THAT IT MAY HAVE BEEN REPLACED BEFORE.
