What was found
RT WING, AILERON CONTROL CABLES, TWO EACH, CHAFED AT RUB-BLOCK INBOARD OF THE AUTOPILOT SERVO. CABLE STRANDS ARE NOT FRAYED, CANNOT DETECT CHAFE DAMAGE WITH RUNNING A RAG OVER THE DAMAGE. BUT STRANDS ARE DEFINITELY CHAFED BEYOND AN AMOUNT TO CAUSE CONCERN. HARD TO DETECT WITHOUT THOROUGHLY CLEANING AND VIEWING WITH A VERY BRIGHT LIGHT AT A CERTAIN ANGLE. READ SIL AND WILL BE LOOKING FOR OTHER CABLES AS MENTIONED IN THE SIL. SUGGEST RUB BLOCK BE REPLACED WITH TWO SMALL PULLEYS.
