## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas MD-11 series airplanes. This action requires the deactivation of the forward and center cargo control units (CCU). This amendment is prompted by a report of failure of a CCU which produced overheating of the electrical pins inside the CCU; the subsequent release of hot gases and flames ignited an adjacent insulation blanket. The actions specified in this AD are intended to prevent such conditions, which could result in smoke and fire in the cargo compartment.
