(1) Remove propeller from the aircraft and remove spacer from the propeller.
(2) Thoroughly remove and clean all paint material down to the anodize surface and inspect the center relief bore (hole), all mounting bolt holes, and all external surfaces in the entire propeller hub area (faces and sides) for cracks using dye penetrant inspection methods.
(3) If a crack is found, replace the propeller with a serviceable propeller before further flight.
