Rather frightening stories actually.
Apparently, a lightning strike seems to be much more damaging on metallic/composite structures (ie. blades with a metallic spar)
Usually, composite parts of airframes I know, include a metalization sheet, but I don't think such a device is found on blades...could it be a reason of such damaging effects on them ?Despite their possible dramatic results,I wonder why lightning strike doesn't seems to be of a primary hazard concern amongst helicopter people. Maybe is it because experience shows they have limited effects on fixed wings ( usually bigger and with less composite components)...maybe is it only just because we consider them as part of our fate ?
