LIGHTNING STRIKE
Because lightning behavior is difficult to predict, conduct a
thorough inspection of 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.
NOTE
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.
Any damage found anywhere on helicopter shall be
recorded in detail stating lightning strike as reason
for removal. Copies of these records shall be
provided along with any component returned or
overhauled to assist overhauling facility in evaluating
component.
