SEATTLE – The National Transportation Safety Board is now analyzing battery cells at a microscopic level for shorts that might have caused the fire aboard a Japan Air Lines 787.

The NTSB says it’s also looking for signs of in-service damage and manufacturing defects, that might have led to the uncontrolled “thermal runaway” of at least one of the battery’s eight individual cells, which likely triggered damage in other cells.  Three cells are heavily damaged, while others are barely touched.

The NTSB is bringing in experts from the Carderock Division of the Naval Surface Warfare Center laboratories to help in its investigation.
