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
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 the hollow sound.
1. Mark off the limits of the delamination using chalk.
