What was found
AFTER LANDING COULD SMELL SOMETHING THAT WAS DESCRIBED AS BURNING CHARCOAL. UPON FURTHER DISCOVERY IT WAS DETERMINED THAT THE BLOWER MOTOR, LOCATED BELOW THE RUDDER PEDALS ON THE LT SIDE, HAD BECOME INOPERATIVE & WAS REPLACED WITH A NEW PART. THE OPERATIONAL CHECK WAS GOOD, NO FURTHER PROBLEMS WITH SYS.
