Airbus Group SE’s earnings fell 3.6 percent last year as a late surge in aircraft deliveries failed to offset costs from ramping up output of the A350 twin-aisle model and the impact of engine glitches that curbed handovers of the latest A320 narrow-body. Earnings before interest and tax before one-time items dropped to 3.96 billion euros in 2016 from 4.11 billion euros a year earlier, Toulouse, France-based Airbus said in a statement Wednesday.
