fuselage section.
4.11.2 Defects. Void damage may occur on any area of the skin/honeycomb structure. This inspection is to verify any
void indications found visually.
NOTE
A void is defined as an unbonded area that is supposed to be bonded. Many sub-
definitions of voids are given such as lack of adhesive, gas pocket, misfit, etc.
However, this manual makes no distinction among these, grouping them all under
one general term ("void").
