Background: The manufacture has advised that a counterweight clamp installed on an HC-E4A-3A propeller separated in flight. The clamp passed through the spinner dome and struck an adjacent blade resulting in a blade failure. One of the two socket head screws attaching the counterweight clamp broke. The failure was due to a defective socket head cap screw.
