We brought a Baron in for a wing bolt inspection.  Normally, the carpets are removed so as to not get them dirty.  This revealed corrosion to the baggage floor skin.

There was evidence of past attempts to control the corrosion by sanding.  We decided to remove the floor for further inspection.  This found bad corrosion to the bottom of the floor, as well as structure in the floor.
