The European Aviation Safety Agency has issued a proposed airworthiness directive for A380s because of cracking on the die-forged front spar on some of the aircraft in service. EASA says the cracks, which occur between Ribs 4 and 8, were found during full-scale fatigue tests. “The condition, if not detected and corrected, could reduce the structural integrity of the wing front spar,” EASA says. The problem is limited to nine A380s in commercial service.
