Shortly after departure, the flightcrew heard a loud pop or crack, and the airplane made an uncommanded roll to the left. In addition, the right generator off light illuminated. By holding continuous input to the control yoke, the airplane was returned to a wings-level attitude, and returned for an overweight landing without incident. Examination of the airplane revealed that one of two aileron cables on the right side aileron control had been severed by electrical arcing from the right engine generator feed line. No evidence of contact between the generator feed cable and the aileron cable was found. However, a pin hole about 1/8 inch in diameter was found on the plastic sheath of the generator feed cable in the area where the aileron cable passed nearby. The Boeing drawing used for production states to maintain a 1.0 inch minimum clearance between the aileron cable and the generator feed line. When the aileron cable was replaced and tensioned on the incident airplane, the clearance between the aileron cable and generator feed line was measured at 3/16 inch.
Probable Cause: the improper installation of the generator feed cable by the manufacturer, which resulted in a severed aileron cable due to arcing between the generator feed cable and aileron cable.
