The very first job this 67y private did was walk down the length of 20 or so kaman main rotor blades with a ball peen hammer and an ultrasound machine looking for voids in the spar which we found plenty of . When a void was found we walked down that blade with that hammer and knocked holes in the blades caned them back up and sent them back to kaman I think the manufacturer kaman 747 blades I want to say. Wild job for a private !
