Airworthiness Directives; Airbus Model A340-200, -300, -500, and -600 Series Airplanes

We are adopting a new airworthiness directive (AD) for the products listed above that supersedes an existing AD. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: * * * * * The revision 01 of Airbus A340 ALS [Airworthiness Limitations section] Part 3 introduces more restrictive maintenance requirements and/or airworthiness limitations. Failure to comply with this revision constitutes an unsafe condition. * * * * * The unsafe condition is a safety-significant latent failure that would, in combination with one or more other specific failures or events, result in a hazardous or catastrophic failure condition. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
