description This invention relates generally to gas turbine engines, and more specifically to nozzle assemblies used with gas turbine engines. A method enables a nozzle assembly for a gas turbine engine rotor assembly to be fabricated. The rotor assembly includes at least two adjacent rows of rotor blades coupled together by a disk spacer arm. The method includes providing a nozzle assembly that includes at least one nozzle including a vane that extends outwardly from a radially outer side of an inner band, coupling the nozzle assembly into the rotor assembly between the two adjacent rows of rotor blades, and coupling a seal assembly that includes a backing piece to the nozzle assembly such that the backing piece is substantially parallel to the rotor assembly disk spacer arm.
