## Discrepancy

SPAR KIT PN 58-4008-9S WAS ORDERED FROM MFG AND UPON INSPECTION OF KIT, PITTING WAS NOTICED ALONG THE EDGE OF THE LT PLATE PN 36-430056-6.  AFTER CLEANING SOME OF THE PRIMER OFF, THE PITTING WAS NOTICED ON THE ALUMINUM ITSELF.  THIS COULD POSSIBLY BE FROM CORROSION.  SINCE THE ORIGIN OF THE PITTING WAS NOT KNOWN A NEW PLATE IS BEING ORDERED FROM MFG.  RECOMMEND INSPECTION OF ALL SPAR KIT PLATES BEFORE INSTALLATION.
