Mark, with regard to an email I sent just a moment ago, please find followings:
1-with regard to file 1.png, why swivel hinge may be used instead of fixed one at Attachment points of elevator and the tab?
2-would you mind explain thoroughly how is clamped hinge different to the slip hinge?
3-how does inspection putty reveal the distress or displacement of the clamp hinge bolt?
4-with regard to files 5.png and 6.png, I believe during wiggle test, the master fitting lug has to be pushed by finger and we would find it remain at rest if it has not been damaged, am I right. Please correct me if I'm wrong.
