SUMMARY: We propose to adopt a new airworthiness directive (AD) for the produc

listed above. This proposed AD results from mandatory conlinuing airworthiness

infolTIlation (MeAT) originated by an aviation authority of another country to identify

and correct an unsafe condition on an aviation product. The MeAl describes the unsafi

condition as:

Surface defects were visually detected on the rudder of one Airbus A319

and one A321 in-service aeroplane. lnvdstigation has determined that the

defects reported on both rudders corresp:onded to areas that had been

reworked in production. The investigation confirmed that the defects were

the result of de-bonding between the skin and honeycomb core. Such

reworks were also perfonned on some rudders fitted on A330-300 and

A340-200/-300 aeroplanes.

An extended de-bonding, if not detected and corrected, may degrade the

structural integrity of the rudder. The loss of the rudder leads to

degradation of the handling qualities and reduces the controllability of the

aeroplane.
