| Regulators around the globe ordered the grounding of Boeing 787s on Thursday until they could determine what caused a new type of battery to fail on two planes in recent days, resulting in an emergency landing on Wednesday and a fire last week. | |
| The directives in Europe, India and Japan followed an order Wednesday by the U.S. Federal Aviation Administration grounding the planes operated by U.S. carriers. | The directives in Europe, India and Japan followed an order Wednesday by the U.S. Federal Aviation Administration grounding the planes operated by U.S. carriers. |
| The decisions are a result of incidents involving a plane that was parked in Boston and one in Japan that had to make an emergency landing this week after an alarm warning of smoke in the cockpit. | |
| In Japan on Thursday, the transportation ministry issued a formal order to ground all 787s indefinitely, until concerns over the aircraft’s battery systems are resolved. All Nippon Airways and Japan Airlines had already voluntarily grounded their 787s on Wednesday, leading to more than two dozen canceled flights. | In Japan on Thursday, the transportation ministry issued a formal order to ground all 787s indefinitely, until concerns over the aircraft’s battery systems are resolved.

| Boeing, based in Chicago, has a lot riding on the 787, and its stock dropped nearly 3.4 percent Wednesday to $74.34. The company has outlined ambitious plans to double its production rate to 10 planes a month by the end of 2013. It is also starting to build a stretch version and considering an even larger one after that. | Boeing, based in Chicago, has a lot riding on the 787, and its stock dropped nearly 3.4 percent Wednesday to $74.34.

| The grounding — an unusual action for a new plane — focuses on one of the more risky design choices made by Boeing, namely to make extensive use of lithium-ion batteries aboard its airplanes for the first time. | The grounding — an unusual action for a new plane — focuses on one of the more risky design choices made by Boeing, namely to make extensive use of lithium-ion batteries aboard its airplanes for the first time. |
| Until now, much of the attention on the 787 was focused on its lighter composite materials and more efficient engines, meant to usher in a new era of more fuel-efficient travel, particularly over long distances. The batteries are part of an electrical system that replaces many mechanical and hydraulic ones that are common in previous jets. | Until now, much of the attention on the 787 was focused on its lighter composite materials and more efficient engines, meant to usher in a new era of more fuel-efficient travel, particularly over long distances.

| The 787’s problems could jeopardize one of its major features, its ability to fly long distances at a lower cost. The plane is certified to fly 180 minutes from an airport. The U.S. government is unlikely to extend that to 330 minutes, as Boeing has promised, until all problems with the plane have been resolved. | The 787’s problems could jeopardize one of its major features, its ability to fly long distances at a lower cost.

| For Boeing, “it’s crucial to get it right,” said Richard L. Aboulafia, an aviation analyst at Teal Group in Fairfax, Virginia. “They’ve got a brief and closing window in which they can convince the public and their flying customers that this is not a problem child.” | For Boeing, “it’s crucial to get it right,” said Richard L.

| In Japan on Thursday, government investigators examined the 787 that made the emergency landing. Footage on the public broadcaster, NHK, showed officials removing a charred and swollen lithium-ion battery pack from the front of the plane. | In Japan on Thursday, government investigators examined the 787 that made the emergency landing.

| Corrosive liquid appeared to have leaked out of the batteries, leaving streaks on their blue casing, said Hideo Kosugi, a safety official who is head of the inquiry. Investigators also found black discolorations outside exhaust vents on the plane, which suggested that there had been smoke inside the aircraft at one point. | Corrosive liquid appeared to have leaked out of the batteries, leaving streaks on their blue casing, said Hideo Kosugi, a safety official who is head of the inquiry.

| “The batteries have retained their basic shape, but are black all over,” Mr. Kosugi said. Something caused the battery to overheat and spew liquid, he added, “but we still do not know what is the cause.” | “The batteries have retained their basic shape, but are black all over,” Mr. Kosugi said.

| The 787 uses two identical lithium-ion batteries, each about one and a half to two times the size of a typical car battery. One battery, in the rear electrical equipment bay near the wings, is used to start the auxiliary power unit, a small engine in the tail that is used most often to provide power for the plane while it is on the ground. The other battery, called the main battery, starts the pilot’s computer displays and serves as a backup for flight systems. | The 787 uses two identical lithium-ion batteries, each about one and a half to two times the size of a typical car battery.

| In a conference call last week with reporters, Boeing’s chief engineer for the 787, Mike Sinnett, said that the company had long been aware of possible problems with lithium-ion batteries but that it had built in numerous redundant features to keep any problems with the batteries from threatening the plane in flight. He said that the batteries had not had any problems in 1.3 million hours of flight and that Boeing was trying to understand what had caused the problems. | In a conference call last week with reporters, Boeing’s chief engineer for the 787, Mike Sinnett, said that the company had long been aware of possible problems with lithium-ion batteries but that it had built in numerous redundant features to keep any problems with the batteries from threatening the plane in flight.

| Mr. Sinnett said that if the lithium-ion batteries started a fire, it would be nearly impossible to put out because the batteries produce oxygen when burning. Mr. Sinnett said that the plane was designed to survive such an event in flight, when the cabin’s air-pressure system protects passengers and allows the plane to vent the smoke outside. The plane is also designed, he said, to contain a fire to a small area. | Mr. Sinnett said that if the lithium-ion batteries started a fire, it would be nearly impossible to put out because the batteries produce oxygen when burning.

| Heat from the fire on the plane parked in Boston last week was so extreme that it melted the bolts holding the battery to the equipment rack. Firefighters had to use a hydraulic tool to cut it loose. | Heat from the fire on the plane parked in Boston last week was so extreme that it melted the bolts holding the battery to the equipment rack.

| The solutions to the battery problem could be simple, analysts said, like encasing the battery in a stronger shell or monitoring the batteries more closely. But if Boeing had to switch to more conventional nickel-cadmium or lead-acid batteries, they would have to be larger, adding more weight to the plane and cutting into the plane’s fuel-savings potential. | The solutions to the battery problem could be simple, analysts said, like encasing the battery in a stronger shell or monitoring the batteries more closely.

| The emergency landing Wednesday was the latest in a string of incidents for the 787, which also included an electrical failure, fuel leaks and other smaller mishaps. But the latest event raised concerns that the 787’s problems were potentially more serious than thought. | The emergency landing Wednesday was the latest in a string of incidents for the 787, which also included an electrical failure, fuel leaks and other smaller mishaps.

| Lithium-ion batteries provide power more quickly than conventional batteries and can be recharged quickly. They are increasingly used in cellphones, computers and electric cars but also have known risks of fires and explosions, particularly if they overheat or overcharge. | Lithium-ion batteries provide power more quickly than conventional batteries and can be recharged quickly.

| Boeing expects to sell 5,000 787s in the next 20 years. It is counting on the Dreamliner in the global sales battle with Airbus, its European rival, which plans to introduce its own carbon-composite plane, the A350, in the second half of 2014. Boeing has said that it outsourced too much of the work on the 787 to suppliers who were willing, collectively, to cover billions of dollars of the development costs, and that many parts needed reworking. | Boeing expects to sell 5,000 787s in the next 20 years.

| Boeing has said it expects profit percentages averaging in the low single digits on the first 1,100 planes, which could include deliveries into 2021. But David E. Strauss, an analyst at UBS, cautioned last month that Boeing’s production costs might remain too high for it to make a profit on any of the plane sales before 2021. | Boeing has said it expects profit percentages averaging in the low single digits on the first 1,100 planes, which could include deliveries into 2021.
