Re: Rod Rigging
You check for forzen fittings and sockets, make sure they are lubricated, and preferably do a dye check or scrutinize them for stress cracks.
NavTec organizes things by what they call a "Class A (B) (C)" inspection, based on the number of years or miles the rigging has been in use. Every so often they call for taking down the whole rig (Class C) to go over all the bits in detail. At shorter intervals, it is just inspected in place. Give 'em a call, sometimes they answer the phone & email.
