Line replaceable fuel injector panels with single hatch installation

A system comprising:

• an engine case for a gas turbine engine defined around a longitudinal axis, wherein an access opening is defined through the engine case for access from outside the engine case to a space inside the engine case;
• and
• a combustor housed in the space inside the engine case, wherein the combustor includes an inner annular wall and an outer annular wall radially outboard from the inner annular wall, wherein the inner annular wall includes a first rail on an upstream end thereof, wherein the outer annular wall includes a second rail on an upstream end thereof, and wherein the first and second rails each include a respective access portion configured to receive line replaceable injector components from through the access opening of the engine case into the first and second rails to form a combustor dome of the combustor, further comprising a plurality of fuel injector components assembled across the first and second rails to form a combustor dome at an upstream end of a combustion space defined between the inner and outer annular walls of the combustor, wherein each of the fuel injector components includes an inner edge with a circumferentially extending dovetail, and wherein the first rail includes a circumferentially extending dovetail slot, wherein the dovetail of each of the fuel injector components is engaged in the dovetail slot.
