## Discrepancy

(CAN) MOMENTARY INTERMITTENT FAILURE IN DESCENT. 'DPU FAILURE' MESSAGE WOULD BE SHOWN. AND IAT WOULD SHUTDOWN, THEN COME BACK ON LINE. NOTE: THIS IS THIRD TIME UNIT. HAS BEEN REMOVED AND SENT TO MANUFACTURER. MANUFACTURER HAS BEEN UNABLE TO DUPLICATE THE PROBLEM BUT NOW HAS SUPPLIED US WITH A REPLACEMENT UNIT.
