A gas turbine engine fan section is disclosed that includes a hub. Circumferentially spaced fan blades are supported on the hub. A spacer is arranged between adjacent fan blades and is operatively supported by the hub. The spacer is configured to be collapsible in response to a fan blade load exerted on the spacer in excess of a threshold load. The spacer is generally rigid at fan blade loads below the threshold load.
