## Abstract

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8 airplanes. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires modification of the battery system, or other actions. This AD was prompted by recent incidents involving lithium ion battery failures that resulted in release of flammable electrolytes, heat damage, and smoke. We are issuing this AD to correct damage to critical systems and structures, and the potential for fire in the electrical compartment.
