## Discrepancy

ON DESCENT, AT 250 KTS WITH WINGS LEVEL, THE SPOILERS WERE EXTENDED TO EXT POSITION.  AFTER A FEW SECONDS, THE SPOILER HANDLE SNAPPED BACK TO THE FORWARD POSITION.  WHEN PULLING THE SPOILER HANDLE BACK TO THE EXT POSITION, THE AIRCRAFT ROLLED 20 DEGREES TO THE LEFT.  THE HANDLE WAS STOWED AND THE ACFT RETURNED TO LEVEL FLIGHT.  THE AUTOPILOT WAS THEN DISCONNECTED.  THE GROUND SPOILERS OPERATED NORMALLY ON LANDING.  MAINTENANCE FOUND CHUNKS OF ICE ON VARIOUS CONTROL CABLES IN THE RT WHEEL DUE TO A POTABLE WATER LEAK.  THE ICE WAS REMOVED AND THE POTABLE WATER SYSTEM WAS DEFERRED.  THE ACFT WAS RETURNED TO SERVICE.
