## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Industrie Model A320 and A321 series airplanes, that requires replacement of two elevator aileron computers (ELAC) with ELAC's that contain new software. This amendment is prompted by a report indicating difficulty maintaining the intended flight path during landing in turbulent conditions. The actions specified by this AD are intended to prevent situations that could lead to reduced controllability of the airplane due to adverse airplane- pilot coupling characteristics.
