This Special Airworthiness Information Bulletin (SAIB) alerts you, owners or operators of Piper Aircraft Inc. (Piper) airplane models (see list of models below), about a potential airworthiness concern regarding failure of the aileron control cables and consequent loss of aileron control authority. This failure is due to a manufacturing flaw in the pulley, which causes the aileron control cables to be severed at the pulley location.
