Wing Installation - Part 2

This blog covers the installation of the aileron and flaps.

Overview
The ailerons and flaps are supplied pre-skinned with the D noses to be removed, trimmed with this task is to be undertaken after the installation of both items onto the wing.

Aileron Hinges

The hinges are stainless steel foldings with the mounting holes slotted to align the aileron the tips and flap. These were fixed with AN3 bolts then lightly nipped allowing adjustment.

With the hinges installed onto the wing, the other mating half was fitted to the ailerons using AN3 bolts and washers.

Note: No nuts are required as all holes are predrilled and fitted with anchor nuts at the factory

Alignment
The jig that was used to align the tip is reused to set the aerilons alignment to the skin, once set the aileron is locked into position with masking tape and rechecked.

Once satisfied we moved to the flaps.aileron

Flaps
The angle brackets are sorted out with their respective mounts with only the outer hinges installed at this time. The hinge arm is fixed to the bracket with AN4 bolts and the bracket then inserted in between the faces of the two [2] angles then clamped with a C clamp mentioned in part 1.

Next, the inboard edge is aligned using the jig and two [2] people to support the flap, with the flap and aileron aligned and checked to confirm that they form a straight line. This required an amount of adjustment at the aerilon then flap until a satisfactory result was achieved.  Once aligned the flap is taped as per the ailerons, and all checked again, and the aerilon bolts were nipped up tight.

Next, the brackets were matched drilled as per the builder manual and bolted. Finally, the centre bracket was swung into position then drill and fixed as per the outer brackets.

At this point, we all stood back and were impressed by our efforts with more coffee to celebrate.

With the flaps disconnected at the hinge point as were, the ailerons and these were placed to one side for later work. The rivet points in the werelion hinge were marked with a 4 mm drill for riveting - these rivets lock in the alignment at that end.

Next job was to remove both wings and install them in the vertical on saw horses to allow kitting out. The remaining nose skins are removed to allow trimming and to fit the fuel tanks.

None really but it did look so cool with the wings on.
