The regional military in my home town has a UH-1 tht they are wanting to suspend from the ceiling of the builidng by using the mast nut. The mast nut has a lifting eye on top of it. Can the aircraft be lifted from teh mast nut? if it can be done, I would assume there are specifications on a lifting bracket and pin. Where could I find the specifications for these components, or find an orignal?
