Airworthiness Directives; Airbus Model A330 and A340 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes. This action requires a one-time operational test to detect discrepancies of the delay valves and check valves of the main landing gear (MLG); and corrective actions, if necessary. This amendment also requires replacement of the retraction bracket assemblies of the MLG with new or reworked retraction bracket assemblies. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent failure of the retraction bracket assemblies of the MLG, which could result in an undampened extension of the MLG, damage to the sidestay and attachment structure, and possible collapse of the MLG.
