One of the issues with the Rt wing was struggling to grasp the alignment concepts and adjust two or three semmingly conflicting points at the same time. Boiled this down to a sequence of issues. 1) Dist from 'chord line' to the pivot point of the W-406/407 is defined = 1 5/8" 2) In-trail position of control surf 'centers' component on the chord line 3) "neutral" position of bellcrank determines aileron pushrod length while in-trail 4) Up & Down travel checked when all components secured
Note - it is easier to 'fix' the aileron position (chord line) on 1 5/8" dist on each W-406/407 attach bracket and then make minor adjustments on the W-413/414 brackets to adjust in-trail.
In #2, it is clear that the 1 5/8" mark is NOT on the chord line of the aileron at this point - and should not be drilled yet. In #1, it is very close and a #40 cleco was arbitrarily drilled to secure the bracket during initial fitting.
#3 shows the alignment of the clord line on the tooling holes of the end ribs. Two flexible 1-by's were also used to check the upper and lower wing/aileron skin alignment in addition to the tooling holes. If a conflict between tooling holes and skins, the skins take precedent in adjustment.
