The European Aviation Safety Agency (EASA) published Friday 20 January 2012 an Airworthiness Directive to mandate a prompt detailed visual inspection of the wings of 20 Airbus A380.
This inspection, which applies to aircraft that have already completed more than 1300 flights, will have to be performed within six weeks of 24 January 2012. Aircraft that have completed more than 1800 flights will have to be inspected within four days of this date.

Following an unscheduled internal inspection of an A380 wing, some rib feet have been found with cracks originating from the rib to skin panel attachment holes (Type 1 cracks according to Airbus All Operator Telex (AOT) terminology). 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.
