The area between the inner and outer aluminum panels is filled with a honeycomb core bonded to the panels with anepoxy adhesive. Separation of this core from the aluminum panel will cause a structural weakness in the affected area.Large delaminations should be repaired as soon as possible.2. Delaminated areas produce a light hollow sound similar to the sound the bottom of an oil can makes when pressed. Abonded area produces a dull solid sound. The sound may change somewhat when crossing structural members.3. Using a tapping hammer, inspect the roof, floor, endwalls, and sidewalls of the inner and outer aluminum panelsattached to structural members for a hollow sound.REPAIR1. Mark off the limits of the delamination using chalk.5-23
