## Discrepancy

DURING INSPECTIONS WE HAVE DISCOVERED A TREND WHERE THE TELEFLEX CABLES THAT CONNECT TO THE FCU POWER CONTROL ARE SHOWING SIGNS OF WEAR CAUSED BY CHAFING AGAINST THE ENGINE LOWER COWLING.  THE MOST SEVERE EXAMPLES OF THIS WERE ON SERIAL NUMBERS SH3205, SH3415, SH3416
WIN AVIATION HAS ADJUSTED THE ROUTING OF THE CABLES SUCH THAT THEY CLEAR LOWER COWL ASSEMBLY, AND HAVE IMPLEMENTED A 90 DAY INSPECTION ON ALL ITS SHERPAS, TO MONITOR THE CONDITION OF THE AFFECTED AREAS OF THE CABLES.
