## Discrepancy

DURING INSPECTION, FOUND FORWARD HORIZONTAL STABILIZER BRACKETS EXFOLIATED.  PIPER SB 962, WHICH PERTAINS TO THIS AREA, HAD BEEN PREVIOUSLY C/W.  THESE BRACKETS ARE HARD TO SEE WITHOUT A MIRROR AND, LIKEWISE, ARE HARD TO CLEAN.  SUBMITTER STATED THIS PROBLEM (CORROSION) IS CAUSED BY 2 THINGS:  INCREASES OF MOISTURE INTO EMPENNAGE, AND DISSIMILAR METALS.  BRACKETS ARE STEEL, STRUCTURE IS ALUMINUM.  IT IS HIGHLY RECOMMENDED THIS BE A MANDATORY REPLACEMENT ITEM AFTER 2 YEARS OR EXPOSURE TO CORROSIVE ENVIRONMENT.
