Abstract
A method of making a rotor blade assembly includes receiving a sheath assembly and a blade body at a blade assembly tool. The sheath assembly is spread by applying force to an interior surface of the sheath assembly. The blade body is inserted within the interior of the sheath assembly, registered with the sheath assembly, and the force removed from the interior surface of the sheath assembly such that the sheath assembly collapses on the blade body.
