Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a crack repair method of a turbine engine component without adversely affecting material characteristics. SOLUTION: In the crack repair method of a turbine engine component, the component is preferably composed of a single-crystal nickel material and has at least one crack. An alloy composition for repair, which contains a single-crystal nickel alloy, a first nickel brazing alloy and a second nickel brazing alloy, is applied to the crack, and the component to which the alloy composition for repair has been applied is exposed to a heat cycle to enhance diffusion of the alloy composition for repair into the crack.
