While identical part numbers, they serve separate. Worldwide, 50 of the Boeing 787 Dreamliners had entered commercial service before the grounding. The fire on board a Boeing 787 Dreamliner at Heathrow last week started in a component carrying lithium batteries, investigators have said, in a blaze that crew would have struggled to contain. The Federal Aviation Administration on Tuesday approved a proposed remedy for problems that triggered battery fires and led to the grounding of Boeings 787 Dreamliner, but the company must. The 787 Dreamliner has two primary rechargeable batteries the main and auxiliary power unit (APU). Other measures include narrowing the acceptable level of charge for the battery. The company's plan, which was approved by the FAA, calls for the batteries to be wrapped in new thermal and electrical insulation materials and encased in a stainless steel enclosure. Last month, Boeing announced that it had developed additional safety features intended to prevent heat issues with the lithium-ion batteries located in the 787's auxiliary power unit. "The purpose of the flight was to demonstrate that the new battery system performs as intended during normal and non-normal flight conditions."īoeing did not elaborate, but said it would gather and analyze data from today's 787 flight and deliver all requisite materials to the FAA "in the coming days." "The crew reported that the certification demonstration plan was straightforward and the flight was uneventful," Boeing said in a statement. Inside the steel battery box, in the absence of free-moving oxygen, the electrolyte can’t ignite. Boeing said that the aircraft flew for 1 hour, 49 minutes today from an airfield in Everett, Wash., with a crew of 11 onboard, including two representatives from the FAA. The fuel in this case is the electrolyte. 787 Dreamliner battery changes Boeing had made 12 changes to the battery. The certification testing wrapped up with a demonstration flight on "line number 86," a Boeing-owned production Dreamliner built for LOT Polish Airlines. Japanese regulators investigating Boeing ’s 787 Dreamliner disclosed on Wednesday that they had so far found no evidence that one of its batteries had failed because of overcharging. Boeing says it has a fix for the battery problems that grounded its new 787 Dreamliner, and tonight executives are answering questions about the fixes. Last week, the US Federal Aviation Authority signalled its approval of Boeing's redesign of the battery system.
