## Discrepancy

(CAN) AS COLD WEATHER ARRIVED LATE SEPTEMBER THE FLAP SYSTEM DEVELOPED MORE FREQUENT FLAP FAILURE INDICATIONS. WHEN TROUBLESHOOTING THE SYSTEM IT WOULD ALWAYS OPERATE NORMALLY IN THE HANGAR. AS A LAST RESORT TO CLARIFY THE PROBLEM THE FLAP ACTUATORS WERE FROZEN WITH CO2 AND THIS CAUSED THE ACTUATORS TO FREEZE SOLID CAUSING A FLAP FAILURE. NEW ACTUATORS WERE ORDERED AND INSTALLED. SYSTEM WAS RIGGED AND OPERATIONALLY CHECKED SERVICEABLE. THIS HAS BEEN AN ON GOING PROBLEM THAT I AM TOLD IS BEING ADDRESSED BY PILATUS.
