What was found
DURING A PRE-BUY INSPECTION, THE LONCOIN RUBBER MATS WERE PULLED UP FROM THE COCKPIT FLOORS. UNDER THE PILOTS SIDE OF THE MATS, MAJOR CORROSION ACCUMULATION WAS DISCOVERED. THESE MATS WERE STILL DAMP UNDERNEATH WHICH SHOWED WHY THIS CORROSION EXISTED. SUSPECT THAT SALT LADEN WATER FROM THE PILOTS FEET DURING WINTER OPERATIONAS CONTRIBUTED TO THIS CORROSION. THE RUBBER MATS ALLOWED THE MOISTURE TO PENETRATE BUT WOULD NOT LET IT DRY. THIS FLOOR PANEL IS COMPLETELY DESTROYED AND MUST BE REPLACED. MORE STRIGENT CLEANING AND INSPECTION PRACTICES MUST BE PRACTICED IN ENVIROMENTS SUCH AS THIS. (K)
