## Discrepancy

PILOT REPORTED THAT WHILE FLYING IN IMC CONDITIONS WITH AUTO PILOT ENGAGED IN HEADING MODE, HE COMMANDED A COURSE CHANGE AND THE AUTOPILOT PERFORMED A TURN IN THE OPPOSITE DIRECTION.  CONDUCTED AT P-STATIC TEST AND FOUND SEVERAL STATIC WICKS NOT BONDED CORRECTLY, ALSO  FOUND THAT WHEN HIGH VOLTAGE APPLIED TO THE PROPELLER THE AUTOPILOT WOULD TURN ITSELF ON AND RANDOMLY GO INTO DIFFERENT MODES.  THE AUTOPILOT AND AIRFRAME MANUFACTURES HAVE BEEN CONTACTED.
