Airline manufacturer Boeing’s newest plane, the 787 Dreamliner, is grounded around the world due to concerns over the lithium battery on which it relies. On January 7, a battery caught fire inside a parked Dreamliner in Japan, raising concerns that similar problems may be prevalent in the new planes. The Federal Aviation Administration, the airline industry’s regulator, relied heavily on data provided by Boeing showing that the lithium batteries “featured redundant safeguards that were essentially foolproof,” the Wall Street Journal reported this morning. And though the airline industry is safer today that it has ever been, the FAA is increasingly relying on airline manufacturers to regulate themselves.
