A combustor for a gas turbine engine includes a liner enclosing a combustion chamber and defining air passages through the liner, a fuel nozzle fluidly connected to the combustion chamber, and a louver disposed inside the combustion chamber over the air passages. The louver extends circumferentially along the liner and is connected to the liner by a fastener. The fastener spacing at least one of axial edges of the louver from the liner to define an air outlet between the at least one of the axial edges and the liner. A method of manufacturing a combustor of an aircraft engine is also disclosed.
