The Federal Aviation Administration has approved the new and improved battery design on the 787 Dreamliner.  That sets the stage for Boeing to implement the fixes on all fifty 787 Dreamliners currently in operation and allows Boeing to once again begin production of the 787.  Since the fleet was grounded in January, Boeing has lost an estimated 600 million dollars in revenue.  The affected airlines including ANA, has said they will ask for compensation adding to the loss for Boeing.  However, word of the approval spread quickly and reactions were ones of sheer elation.  Washington Aerospace Partnership tweeted, “We’re back in business baby!” The FAA said that next week it will tell airlines what changes to make and will publish a directive that “will allow the 787 to return to service with the battery system modifications.”  A spokesman for the FAA said, “before the planes can fly, they must be fitted with a “containment and venting” system for both the two lithium-ion batteries on the 787.  Following FAA approval, Boeing began conducting regular flights of the Dreamliner so it can deliver the planes to customers without further delay.  In addition, Boeing has also dispatched teams around the world to fix the battery issue in the fifty active aircraft as quickly as possible, so the airlines can begin flying them once again.  In approving the Boeing battery fix the FAA has been convinced that the possibility of any future lithium-ion battery fires has been eliminated or at least, reduced enough to once again certify the Dreamliner as safe to fly.  While the grounding of the Dreamliner has been unfortunate, any time an entirely new aircraft is introduced, there is a risk or probability of problems occurring.  The largest commercial airliner, the A380 also experienced serious issues when first brought in to service, including engine problems and minor cracks in the wings.
