Airworthiness Directives; McDonnell Douglas Model MD-11 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that requires replacement of the insulation blankets of the forward and center cargo compartments in the area of the cargo control units (CCU) with new insulation blankets. This action is necessary to protect against electrical failures in the CCUs, which could result in sparks or flame in the CCU container and lead to fire in the insulation blanket or adjacent equipment. This action is intended to address the identified unsafe condition.
