Question for the group... Working on the rear spar for the elevators, the inboard and outboard doublers have 4 holes that do not have a corresponding punched hole in the elevator spar (E-702). There are 8 holes in the doublers and only 4 corresponding holes in the spar. Am I supposed to drill the 4 additional holes into the spar? For further reference, these holes are in each corner of the doublers. Drawings and plans don't mention it (could be that I don't see it).

Service Bulletin
You may want to consider installing the service bulletin parts on those outboard elevator hinge locations now while it is very easy. Otherwise, you will need to inspect the spar for cracking at those rivets annually forever. Installation of the reinforcing kit is terminating action for the service bulletin.

Just for clarification, the original poster is building elevators. The service bulletin referenced above is for the outboard hinge brackets on the horizontal stabilizer.
