## Discrepancy

CYCLIC STICK WOULD PULL HARD FORWARD WHEN COLD.  CUSTOMER REMOVED SERVO AND SENT IN FOR REPAIR.  RECEIVED UNIT AND BOOT WAS TORN AROUND INPUT VALVE.  FUNCTIONAL TEST UNIT FOUND, NO PROBLEM.  PUT UNIT IN FREEZER AND INPUT WOULD BECOME LOCKED UP.  DISASSEMBLED UNIT AND FOUND WATER BEHIND INPUT VALVE.  TORN BOOT ALLOWED WATER TO ENTER INPUT VALVE.
