Washington: At the time the US government certified Boeing's 787 Dreamliners as safe, federal rules barred the type of batteries used to power the airliner's electrical systems from being carried as cargo on passenger planes because of the fire risk.
Now the situation is reversed. Dreamliners worldwide were grounded nearly three weeks ago after lithium ion batteries that are part of the planes led to a fire in one plane and smoke in a second. But new rules exempt aircraft batteries from the ban on large lithium ion batteries as cargo on flights by passenger planes.
In effect, that means the Dreamliner's batteries are now allowed to fly only if they're not attached to a Dreamliner. The regulations were published on Jan 7, the same day as a battery fire in a Japan Airlines 787 parked at Boston's Logan International Airport that took firefighters nearly 40 minutes to put out.
