Batteries have US' OK to fly, but Dreamliners grounded

The situation is reversed now.

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. The timing of the two events appears coincidental.

Pilots and safety advocates say the situation does not make sense. If the 787's battery system is too risky to allow the planes to fly, then it's too risky to ship the same batteries as cargo on airliners, they said.

“These incidents have raised the whole issue of lithium batteries and their use in aviation,” said Jim Hall, a former National Transportation Safety Board (NTSB) chairman. “Any transport of lithium batteries on commercial aircraft for any purpose should be suspended until (an) NTSB investigation is complete and we know more about this entire issue.”

Chesley “Sully” Sullenberger, a former U.S. Airways pilot famed for his precision flying that enabled passengers and crew to survive an emergency landing on the Hudson River in New York, said in an interview that he wouldn't be comfortable flying an airliner that carried lithium ion aircraft batteries in its cargo hold.

“The potential for self-ignition, for uncontained fires, is huge,” he said. The new regulations “need to be looked at very hard in the cold light of day, particularly with what has happened with the 787 batteries.”

The battery rules were changed in order to conform U.S. shipping requirements with international standards as required by Congress, the federal Pipeline and Hazardous Materials Safety Administration said in a statement.
