Disclosed herein is a propeller blade assembly (10) comprising an airfoil (22) having a base (24), a tip (26) and a leading edge (28) and a root (30) extending from the base (24) of the airfoil (22) for attaching the airfoil (22) to a hub. The assembly (10) further comprises an electrically conductive sheath (40) for electrically grounding the airfoil (22). The electrically conductive sheath (44) is attached to the leading edge (28) of the airfoil (22) and extends from the base (24) to the tip (26) of the airfoil (22). The assembly (10) further comprises an electrically conductive element (50) for electrically connecting the electrically conductive sheath (40) to the root (30) or hub. Also disclosed is an electrically conductive sheath (40) for grounding an airfoil (22) and a method for assembling a propeller blade assembly (10).
