F.A.A. Expected to Approve Fix to Dreamliner Batteries

Source: NYT

The Federal Aviation Administration is expected on Friday to approve Boeing’s plans to fix the batteries on its new 787 Dreamliner jets, a decision that could soon allow the planes to return to service after being grounded for more than three months.

People briefed on the matter said the F.A.A. administrator, Michael P. Huerta, and Transportation Secretary Ray LaHood were satisfied that Boeing’s changes would virtually eliminate concerns that the lithium-ion batteries could erupt in smoke or fire.

Their decision could enable the innovative planes to begin flying again in May after they are refitted with more insulation between the battery cells and a new system for venting smoke or hazardous gases out of the planes.

Aviation analysts said the problems had cost Boeing hundreds of millions of dollars and slowed its progress in fielding the planes, which reduce fuel costs by 20 percent and have been in great demand by the airlines.

So.. wrap it in a blanket, and just in case, vent it to the outside? That's the fix? AtheistCrusader Apr 2013 #1

Has to be more to this story, like a redesign of the battery itself, or the charging circuit...
