Airworthiness Directives; Airbus Model A320 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 series airplanes. This action requires reinforcement of the fuselage frame (FR) 20 between stringer 30 and 32 in the forward fuselage. This amendment is prompted by the results of fatigue testing, which revealed that fatigue cracks can develop on the web and cap of lower left FR20. The actions specified in this AD are intended to prevent the initiation and propagation of such fatigue cracking, which could adversely affect the structural integrity of this area of the fuselage.
