## Discrepancy

ICE FORMED INSIDE TAIL ROTOR SLIDER ASSEMBLY AFTER TAKE OFF DUE TO SUB FREEZING TEMPERATURES.  NOTE: A/C EXPOSED TO RAIN PREVIOUS DAY AT OAT NEAR 60 F.  AFTER FRONTAL PASSAGE OAT DROPPED TO 9*F, BUT AIRCRAFT WAS STORED IN DRY HANGER FOR 12 HOURS PRIOR TO FLIGHT.  AFTER STUCK PEDAL OCCURANCE, PART WAS GENTLY WARMED USING HEAT GUN AND MOISTURE WAS OBSERVED DRIPPING FROM PITCH CONTROL ASSEMBLY.
