AVIATION watchdogs have pinpointed the origin of a battery fire that caused a 787 Dreamliner into an emergency landing last month, and said tests on Boeing’s new planes may have misjudged the risk of fire.

The US National Transportation Safety Board said yesterday it is still investigating the underlying cause of the “smoke event”.

But it noted that Boeing’s tests on the 787 failed to properly estimate the degree of risk caused by the lithium ion battery.

All 50 Dreamliners in use have been grounded since 16 January.
