DURING THE NIGHT INSTRUMENT LANDING SYSTEM APPROACH, THE FIRST OFFICER WAS UNABLE TO KEEP THE AIRPLANE ALIGNED WITH THE LOCALIZER. THE CAPTAIN TOOK THE CONTROLS AND WAS FORCED TO UTILIZE FULL RIGHT AILERON AND FULL RIGHT AILERON TRIM TO KEEP THE AIRPLANE LEVEL. A MISSED APPROACH WAS EXECUTED AND AN EMERGENCY WAS DECLARED. THE CREW PERFORMED ANOTHER APPROACH WITH 'SEVERE AILERON PROBLEMS' BUT LANDED SAFELY. AN EXAMINATION REVEALED A SEPARATED AILERON CABLE. METALLURGICAL ANALYSIS REVEALED THAT THE CABLE WAS SEVERELY WORN, WHICH CAUSED THE SEPARATION. THE AIRPLANE UNDERWENT A 'C' CHECK INSPECTION ABOUT 2,582 HOURS PRIOR TO THE INCIDENT. NO RECORDS WERE FOUND TO INDICATE THE AILERON CABLES WERE ADEQUATELY INSPECTED OR REPLACED.
Probable Cause: THE OPERATOR MAINTENANCE PERSONNEL'S FAILURE TO PERFORM AN ADEQUATE INSPECTION OF THE AIRPLANE, WHICH LED TO A WORN AILERON CABLE WHICH SEPARATED IN FLIGHT AND CAUSED A LOSS OF CONTROL.
