The Federal Aviation Administration is asked to issue an airworthiness directive for Textron Lycoming 0-360 series engines with constant speed propellers, requiring that aluminum nuts and elbows used to attach the propeller governor oil line be replaced with steel components. This must be done at the next engine overhaul or whenever the oil line is removed for any reason.
