FAA Proposes Supplemental Airworthiness Directive for McCauley Propeller Systems Model 4HFR34C653/L106FA Propellers
The Federal Aviation Administration (FAA) has proposed a supplemental airworthiness directive requiring fluorescent penetrant inspection (FPI) and eddy current inspection (ECI) of the propeller hub for McCauley Propeller Systems model 4HFR34C653/L106FA propellers to prevent potential failure of the propeller hub, which could lead to blade separation, damage to the aircraft, and loss of control.
