I went back into the shop and decided to pull the left wing flap from its hanging place on the wall and fit the flap and check the hinge pins. With all the hinge pins cut and fit by the last builder, all I had to do was put them on and check them out. My wife Kathryn helped by putting the pins in while I held the flap in place and from falling. She is a great helper! Sharper than a lot of maintenance guys I work with!
The flap went on fine and all looks good. Another thing checked off! Going to be on fuse soon!
