## Summary

This document proposes the supersedure of an existing airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that currently requires repetitive general visual inspections of the power feeder cables, terminal strip, fuseholder, and fuses of the galley load control unit (GLCU) within the No. 3 bay electrical power center to detect damage; and corrective actions, if necessary. This action would require replacement of the electrical wiring of the galley in the electrical power center in bays 1, 2, and 3 with larger gage cable assemblies, which would terminate the repetitive inspections. The proposed AD also expands the applicability of the existing AD to include two additional airplanes. This action is necessary to prevent damage to the wire assembly terminal lugs and overheating of the power feeder cables on the No. 3 and 4 GLCU, which could result in smoke and fire in the center accessory compartment. This action is intended to address the identified unsafe condition.
