Brief Description: Fuel transfer pump installation
Pre-drill the douber, put in place and drill/cleco. Then prime the part for corrosion proofing. Then rivet the doubler to the lower skin of the wing. The rivet press could not reach all the rivets, so we used the rivet gun on one side (me) and Christoph held the bucking barr on the other side. This is practice for closing the wing.
