Used shear to trim reinforcement plates to final size. Installed sheet metal parts to ensure fuel valve and line is located the same as it will be in the final assembly. Connected right fuel line to the Andair valve. Determined location for the reinforcement plate on the right side and drilled holes for blind rivets. Removed fuel line and used a step drill and Dremel drum sander to open up the holes in F-783B R bracket to clear the new mounting holes. In some places the grommet edge covers two layers of sheet metal. The maintenance manual was updated with information about the new brackets and the grommet part numbers. Researched and found more parts and supplies for fiberglass class and for future maintenance. Ordered parts from McMaster and Aircraft Spruce.
