As reported to the FAA. Reports are unverified, and codes are left as the FAA publishes them.

What was found

(CAN) DURING IMPORT INSPECTION THE AILERON CABLES WERE REMOVED FOR INSPECTION. THE LT AILERON BALANCE CABLE WAS SEVERELY FRAYED, AS MUCH AS HALF THE STRANDS BROKEN. THIS WAS AT THE LOCATION IN THE FLAP COVE AREA AT THE PHENOLIC WEAR BLOCK. THIS IS THE WORST CASE WE HAVE SEEN YET OF THE 6 MODELS WE HAVE INSPECTED FOR THIS CONDITION. THE FIX IS TO REPLACE THE SS CABLES WITH GALVANIZED CONTROL CABLES.
