Airbus has said it is confident that the lithium
ion (Li-ion) main battery architecture it has been developing with
Saft and qualifying for the A350 XWB aircraft is robust and safe,
and as such the A350 XWB flight test programme will
continue as planned with the qualified Li-ion main batteries.
However, as the root causes of the two recent
industry Li-ion main batteries incidents remain unexplained,
Airbus has decided to activate its “Plan B”, and revert back to
the proven and mastered nickel cadmium main batteries for its A350
XWB programme at Entry into Service (EIS).
Airbus has also launched additional
maturity studies on Li-ion main batteries behavior in aerospace
Airbus said it does not expect this decision to
impact the A350 XWB Entry Into Service schedule.
