Today we started the alignment of the left flap and aileron. In the neutral position, the flaps and aileron should follow the airfoil shape of the wing ribs. As per the manual, this was done by clamping a straight edge material to the wing rib cap strip and extending it outward to set the flap and aileron position.

A 1/8" gap between the wing trailing edge and flap/aileron leading edge is required per the manual. This was accomplished by using 1/8" wooden wedges taped into position.

A lot of time was spent "tweaking" the positions of the flap and aileron to get an equal gap and to make sure the flap and aileron were inline with each other. Once the position of the two parts were set, we aligned the mating attach brackets on each side of the wing rib web. The brackets were tightly clamped and the four rivet holes were drilled through the previously drilled pilot holes, wing rib web and mating bracket. The final hole size was made using a #30 drill bit in a right angle drill due to limited space. Long reach wing-nut clecos were used to temporarily clamp the parts. Hours: 3.5
