Hi,
So .. this is a minor problem ...
Further to this finding, inspections were carried out on a number of other
aeroplanes where further cracks have been found. During one of those
inspections, a new form of rib foot cracking originating from the forward and aft
edges of the vertical web of the rib feet has been identified (Type 2 cracks
according to Airbus AOT terminology). The new form of cracking is more
significant than the original rib foot hole cracking. It has been determined that
the Type 2 cracks may develop on other aeroplanes after a period of time in
service.
This condition, if not detected and corrected, could potentially affect the
structural integrity of the aeroplane.
For the reasons described above, this AD requires a Detailed Visual Inspection
(DVI) of certain wing rib feet. This AD also requires reporting the inspection
results to Airbus.
