INSPECT
1. The area between the inner and outer aluminum panels is filled with a honeycomb core bonded to the panels with an
epoxy 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. A
bonded 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 panels
attached to structural members for a hollow sound.
REPAIR
1. Mark off the limits of the delamination using chalk.
