No root-cause fix? Sounds like a patch to me.

Just saw it returning to Everett a while ago. Was wondering what it was doing up north - we don’t see airliners larger than 737s up here very often. (Naval airspace here.)

... what it says is a fix ... so that any meltdown of the lithium-ion battery will vent the hot gases outside of the plane.

In other words, there will still be battery meltdown. They haven't fixed the problem yet, but hope the plane is not damaged when it occurs.

The only permanent fix is to change the batteries for a different Lithium formula that is less flammable. But that would mean an 18 month grounding while the new battery and charger system goes through full certification.

If the FAA approves this isolation box fix, that would give Boeing the time to work out a better fix.
