In the first quarter of 2013, revenue at Eurocopter fell by 13 percent, to €1.04 billion ($1.35 billion), with deliveries of 58 helicopters during the three-month period. Parent company EADS attributed the downward performance to the ongoing “technical problems with the Super Puma/EC225 fleet.” Affected have been both deliveries and the service revenue generated by helicopter operations. In the first three months, Eurocopter booked net orders for 51 helicopters, the company said.
