Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Airbus models, as specified above. This AD requires modifying the aft pressure bulkhead for improved corrosion protection and drainage, and related concurrent actions. This AD results from severe corrosion found in the lower rim area of the aft pressure bulkhead during routine maintenance of an airplane. We are issuing this AD to prevent corrosion on the inner rim angle and cleat profile splice of the aft pressure bulkhead, which could result in the loss of airplane structural integrity.
