Airbus A380 wing rib case history
Cracks were first discovered in December last year, on a Qantas-owned Airbus A380 that was being repaired after an engine explosion in Singapore. The Rolls Royce engine failure was caused by a fatigue failure in a fuel line pipe.
The European Aviation Safety Agency EASA took steps and grounded 20 A380 aircraft for visual inspection. These aircraft were early-delivery airframes (airframes without engines). This initial directive allowed up to 6 weeks for visual inspections to be carried out on aircraft which had flown between 1,300 and 1,799 flights. Aircraft which had completed more than 1,800 flights had to be inspected within 4 days.
