## Discrepancy

WHILE PERFORMING A UNIFORMITY INSPECTION. FAA INSPECTORS DISCOVERED THE LT AND RT LOWER AILERON CABLES FRAYED WHERE THEY EXIT THE LOWER WING SKIN AT THE FAIRLEAD, APROXIMATELY 4 INCHES FROM THE THIMBLE EYE SPLICE.  FAA INSPECTORS DISCOVERED THE LT AND RT LOWER AILERON CABLES FRAYED WHERE THEY EXIT THE LOWER WING SKIN AT THE FAIRLEAD, APPROX 6 INCHES FROM THE THIMBLE EYE SPLICE.
