LIGHTNING STRIKE
In all of the following instances, if significant damage
has been found in any area, inspection shall be
expanded in those areas until it extends beyond the
zone of damage. Scrap any component that shows
evidence of severe arc burns.
Because lightning behavior is difficult to predict,
conduct a thorough inspection of the entire
helicopter. Lightning damage may appear as burn
marks, heat discoloration, arc marks, or small weld
marks (where metal has melted and resolidified).
Honeycomb and other composite materials may
exhibit delamination.
