Method for repair and replacement of combustor liner panel

A method for refurbishing a combustion chamber of a gas turbine engine, comprising the steps of:

• removing a combustor from the combustion chamber of the engine;
• removing the inner liner assembly aft of a forward bolt flange, the inner liner assembly farther comprising a multi-hole panel region at its proximal end adjacent to the forward bolt flange and a distal end farther comprising an aft lip region aft of the multi-hole panel region, an aft seal flange region extending from the aft lip region and an aft panel support leg extending from the aft seal flange region;
• separating the multi-hole panel region from the inner liner assembly aft of the forward bolt flange;
• separating the aft panel support leg from the aft seal flange region;
• discarding the separated multi-hole panel region, the aft lip region and aft seal flange region;
• providing a replacement multi-hole panel region and an aft lip region/aft seal flange region;
• inspecting and refurbishing the aft panel support leg and the forward bolt flange;
• joining the replacement multi-hole panel region to the replacement aft lip region/aft seal flange region at an aft lip region joint prep;
• joining the refUrbished aft panel support leg to the aft seal flange region;
• joining the replacement multi-hole panel region to the inner liner assembly aft of the refurbished forward bolt flange to reform the inner liner assembly;
• and
• coating exposed metal surfaces of the reformed inner liner assembly with a thermal barrier coating system.
