A propeller blade assembly comprises a propeller blade having a blade root for attaching the propeller blade to a hub. The blade root has a radially outer surface. The assembly further comprises a collar mounted to the blade root. The collar comprises at least two collar segments assembled around the radially outer surface of the blade root. Each collar segment has a radially inner surface, an opposed radially outward surface and first and second circumferential end lugs. The lugs receive fasteners for coupling the collar segments together to form the collar. The collar segments are formed from a flexible plastics material and the radially inner surface of each collar segments engages the radially outer surface of the blade root only over a limited circumferential extent of the collar segment.
