## Discrepancy

FOUND BROKEN AILERON CABLE STRANDS ON LH AND RH WING CABLES, 2EA P/N 505-15135-405 WHILE PERFORMING DVI INSPECTION ON TASK CODE 27-11-02-002 FOR A 3200 HR/60 MONTH INSPECTION. THE CABLES HAVE NO INDICATION OF WEAR AND HAVE MULTIPLE STRANDS BROKEN ON THE UPPER SIDE OF THE CABLE LOCATED AT A PULLEY. THE LOCATION OF THE PULLEY IS FWD OF SPAR 1 AND RIB 14. THIS IS AN ABNORMAL DEFECT AND WAS ONLY DETECTED WITH A FLASHLIGHT AFTER CLEANING THE CABLES. STRANDS ARE BROKEN SMOOTH AND DO NOT CATCH A RAG WHEN WIPED. THE CABLES APPEAR TO BE BRITTLE AND INDIVIDUAL STRANDS HAVE BROKEN IN HALF. THIS CONDITION WAS FOUND IN BOTH WING LEADING EDGES AT A PULLEY THAT IS A VERY MINOR BEND. THIS IS THE SECOND AIRCRAFT FOUND WITH THIS CONDITION AND HAS BEEN REPORTED TO THE AIRCRAFT MANUFACTURER EMBRAER UNDER CASE NUMBER EEJ-04208814
