The acoustic honeycomb plug is adhesively bonded in the gpanel us- ing a honeycomb seam. The honeycomb seam is composed of a honeycomb sup- port that is located within the seam channel and an adhesive. Using honeycomb seams to adhesively bond acoustic honeycomb plugs into acoustic honeycomb panels is useful in repairing damaged areas of acoustic honeycomb panels that are located in the acoustic treatments for jet engines. -,\•44‘\•4• . * ‘N•4 ' . ` aw d. `\"\•/ \" .
