## Abstract

The FAA is adopting a new airworthiness directive (AD) for McCauley Propeller Systems propeller assemblies, part numbers (P/Ns) B5JFR36C1101/114GCA-0, C5JFR36C1102/L114GCA-0, B5JFR36C1103/114HCA-0, and C5JFR36C1104/L114HCA-0, installed on BAE Systems (Operations) Limited Jetstream Model 4100 series airplanes. This AD requires a one- time eddy-current inspection of the propeller hub for cracks, and if necessary, replacing the propeller assembly. This AD results from three reports of cracked hubs. We are issuing this AD to detect cracked hubs, which could cause failure of the propeller hub and loss of control of the airplane.
