New Zealand’s Air National has relinquished its AOC, giving up its fight to return to the air. The airline has been grounded since early February. The initial 10-day grounding, imposed for what the Civil Aviation Authority (CAA) called “an appalling history of non-compliance with minimum safety standards”, was extended twice. Air National had appealed the grounding, but it was upheld by the Court of Appeal. On 10 March, Air National chief executive Jason Gray sent a letter to the CAA surrendering its AOC, even as it accused the CAA of working to put the airline out of business. Air National had operated New Zealand’s largest charter fleet, including a BAe 146-200, ZK-ECO (msn E2130), which is currently parked at Auckland Airport along with several of the airline’s other aircraft.
