These are pictures of some repairs we did for one of our customers that has a fleet of Metro's. After a hard landing we replaced the lower chord to the inboard side of the left pylon, along with the skin. The other is to the main entry door lower skin. The skin cracks were repaired with two doublers made out of stainless steel. It also required the hinge replacement.   Other pictures are of wing skin corrosion that was repaired.
