Boeing Co.’s global fleet of 787 Dreamliners was grounded, with airlines suspending service on the most advanced civil airliner, to comply with an order from regulators following an emergency landing by one of the planes.

The Federal Aviation Administration instructed airlines to prove that lithium-ion batteries in the model, which went into service in late 2011, “are safe and in compliance,” prompting regulators in Europe and Japan to follow suit and putting all 50 Dreamliners operated by eight airlines worldwide out of duty.
