Zusammenfassung:	PROBLEM TO BE SOLVED: To enable cost-efficient and reliable replacement of a panel of a liner of a combustor since the replacement is a process requiring cost and long time although thermal fatigue occurs on the panel, fragility and/or crack is formed inside of the panel to require replacement of the panel if thermal stress is induced inside of the panel during operation and operation is continued with receiving thermal stress. SOLUTION: A method for repairing the combuster liner of the combustor of a gas turbine engine including a combustion zone formed by an inside liner and an outside liner comprises a process for removing a deteriorated section of the liner and removing a part of the combustor liner for forming fracture, a process for providing a thermal barrier material 110 applied on a replacement panel 240 having at least one opening part 96 and a replacement panel 240 adjacent to the opening part 96, and a process for installing the replacement panel 240 on the fracture section.
