Elevator Install - Part 6

The elevator must be installed on the stab before the rudder can be installed as all practical access will be lost.

Wiring

The skin on the port elevator with the trim was not been fully riveted allowing the cable from the trim motor to the fuselage to be installed and secured correctly. A maintenance loop was stored in the first bay with oversize nylon clamps allowing the loom to slip through while supporting the cable away from the metal.

Cable supports fixed to lower skin

The cables were mounted onto the top side of the turtle deck using nylon clamps and stainless steel mounting brackets. These will be covered with the dorsal faring which will be fixed with M3 counter sunk screws and riv nuts to provide future access. The trim tab will be accessed via the side faring which will be secured in a similar manner.

These were also made removable to provide access to various points for future maintenance of all types.

Note: Doing it again I would have moved the connections to the elevator cover to allow access via faring for maintenance.

Fitting Elevator

All the necessary AN3 bolts and nuts were assembled and the elevator then fitted to the main spar. All of the bolts with little force required to align and insert the bolts through all three components.

Comment: Fitting bolts in this bolts here is an extreme finger sport but a long time ago, the tool below was purchased for this task. I have no idea what its called or where to get one again but if you see one, get hold it by all and any means available.


A bolt is loaded as shown and the tool allow's a bolt to be inserted with relative ease in tight places like rudders, elevators and ailerons.

There a a few more checks to do and a couple of small jobs then the rudder stab can be reinstalled.
