Summary:PURPOSE: A safety test device for a lifting jig for a CPP(Convertible Pitch Propeller) blade is provided to lift the blade in a safe state. CONSTITUTION: A safety test device(1) for a lifting jig for a CPP blade comprises a lug base(10) and a measuring unit(20). The lug base is placed on the bottom surface. Coupling flanges(14) formed on both sides of the top of the lug base are coupled to coupling holes(218) of a body(211) of the lifting jig by connection rings(12). The measuring unit applies pressure to the body of the lifting jig and displays the applied pressure to measure a point of time that the body is deformed.
