The attachment of the doublers went well. The task is made all the easier by the fact that they cdan all be done using the pneumatic squeezer.
I make a small addition to the plans here to include the static bonding attachment points. These replace one of the rivets attaching the doubler. In this scenario, the AN470AD4-4 is replaced by a #8 screw and two AN470AD3-4 rivets. A good safe trade off. The attachment pooints are on the outermost doubler on each of the elevators.
