Requires one-time and repetitive eddy current inspections of the camber side of the blade surface.
Full official abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to McCauley Propeller Systems 4HFR34C653/L106FA-0 model propellers that are installed on Jetstream Series 3200 airplanes. This action is also applicable to 4HFR34C653/L106FA-0 model propellers that are installed on Ayres S2R-G5 and S2R-G10 airplanes if the propeller was previously installed on Jetstream Series 3200 airplanes or if installation history of the propeller is unknown. This action requires one-time and repetitive eddy current inspections of the camber side of the blade surface. This amendment is prompted by a report of a crack on the camber side of the blade surface. The crack was found during a dye penetrant inspection as part of a normal overhaul process. The actions specified in this AD are intended to detect cracks that could cause failure of the propeller blade, which can result in loss of control of the airplane.
