## Discrepancy

WHILE FLYING, A BURNING SMELL WAS OBSERVED AS WELL AS VISIBLE SMOKE COMING FROM THE E-BAY. A PRECAUTIONARY LANDING WAS PERFORMED AND IT WAS DETERMINED THAT THE TRU HAD MALFUNCTIONED. THE #1 TRU WAS CONSIDERABLY HOTTER TO THE TOUCH, AND THE SAME SMELL WAS OBSERVED EMANATING FROM THE FAN PORT IN THE TRU. THE TRU WAS REPLACED AND THEN OPERATIONS CONTINUED AS NORMAL.
