Boeing reportedly offers workaround fix for 787s

A Boeing team led by chief executive Ray Conner presented the plan to FAA head Michael Huerta. The airliners, Boeing’s newest and most technologically advanced, have not been allowed to fly since mid-January.

That would be achieved by placing more robust ceramic insulation around each of the battery’s eight cells.

The plan will require partially recertifying the safety of the batteries, said the officials, who spoke on condition of anonymity because they weren’t authorized to speak publicly.
