Airworthiness Directives; McDonnell Douglas Model MD-11 Series Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This action 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 amendment is prompted by an incident of no power to the aft galleys and two incidents of sparking sounds coming from the G3 galley due to damage of the No. 3 and 4 wire assembly terminal lugs and overheating of the power feeder cables on the G3 GLCU. The actions specified in this AD are intended to prevent such damage due to the accumulated effects over time from overheating of the power feeder cables on the G3 GLCU, which could result in smoke and fire in the G3 galley.
