Immediate software change on ‘significant number’ of jets to result in disruption to half the worldwide fleet

Airlines around the world cancelled and delayed flights heading into the weekend after Airbus announced on Friday that it had ordered immediate repairs to 6,000 of its A320 family of jets in a recall affecting more than half of the global fleet.

The European Union Aviation Safety Agency (EASA), which is the main certifying authority for A320 aircraft, issued the instruction on Friday night as a precautionary action, saying that “safety is paramount”.
