Airworthiness Directives; Airbus Model A320 and A321 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 and A321 series airplanes, that requires activation of a spoiler function that allows partial ground spoiler activation with only one main landing gear compressed. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent possible delays in deceleration when landing with strong cross winds and/or on a contaminated runway, which could increase the potential for landing overrun.
