An engine nacelle structure including a fan duct having a fan duct wall. The fan duct wall including a latticed frame having circumferentially extending frame members and longitudinally extending frame members, the circumferentially extending frame members and longitudinally extending frame members form a plurality of bays therebetween, and a plurality of acoustic attenuation panels, each acoustic attenuation panel being removably coupled to the latticed frame within a respective one of the plurality of bays so that the acoustic attenuation panel is configured to be coupled to and removed from the latticed frame independent of other ones of the plurality of acoustic panels.
