Boeing’s 787 was the subject of industry and governmental scrutiny earlier this year when lithium-ion batteries failed on two Dreamliner jets. Those incidents prompted the U.S. Federal Aviation Administration to ground the 787 on Jan. 16.
The National Transportation Safety Board launched an investigation into the initial battery fire on a Japan Airlines 787 parked at Boston’s Logan International Airport. The NTSB later held a two-day forum on the use of lithium-ion batteries in transportation. It also convened a two-day hearing on Jan. 7 incident.
The U.S. Senate Transportation Committee also held a hearing in April on the 787 incidents.
Boeing redesigned the 787’s battery system, a solution the FAA endorsed. The agency cleared the Dreamliner to return to commercial service in April. Boeing said on Thursday that it delivered seven 787s in May, the first Dreamliners delivered since the grounding.
