A method for repairing a damaged portion of a combustor inner liner assembly. The method includes removing the combustor from a gas turbine engine. After inspecting the combustor to determine whether cracks exists in portions of the inner liner assembly, the method includes removing a cracked inner liner assembly from the combustor. Then the portion of the inner liner assembly, comprising a multi-hole panel region, an aft lip region, an aft seal flange region and an aft panel support leg are separated from the inner liner assembly. The multi-hole panel region and aft lip, where fatigue damage typically exists, along with the aft seal flange region, are discarded and a new aft lip region/aft seal flange region and multi-hole panel region are provided. The new parts are joined to the aft panel support leg and the inner liner assembly aft of forward bolt flange region after these parts are refurbished. The inner liner assembly is then reattached to the combustor and reassembled into the engine.

Method for repair and replacement of combustor liner panel

A method enables a portion of combustor dome assembly to be replaced. The dome assembly includes at least one dome cup including at least one swirl cup including a joint that defines a slot therein, and a deflector plate assembly that is coupled to, and extends downstream from, the swirl cup, such that a portion of the deflector plate assembly is securely fixed within the joint slot. The method comprises cutting through an interface formed between the deflector plate assembly and the joint slot, extending the cut substantially between the deflector assembly and the joint slot through the at least one dome cup, removing the deflector plate assembly from the combustor dome assembly, and coupling a replacement deflector plate assembly within the combustor dome assembly that extends aft from the portion of the combustor dome assembly that is upstream from the cut.
