## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that requires replacement of 10 amp circuit breakers with 5 amp circuit breakers in the left and right windshield anti-ice power controllers; and replacement of the anti-ice control panel with a new or modified panel, or modification and reidentification of the anti-ice control panel. This amendment is prompted by reports of smoke and sparks emanating from the anti-ice control panel in the cockpit. The actions specified by this AD are intended to prevent burnt internal circuit boards caused by a short in either the engine or airfoil anti-ice valve, or the windshield anti-ice controller, which could result in smoke in the cockpit.
