DISCUSSION: Removing a Canard
1) Reach up inside the right leg hole in the instrument panel. Disconnect the control push tube, there should be a quick disconnect located about 12 inches forward of the front control stick. Reassemble the hardware so you don't loose it.
2) Reach up inside the left leg hole in the instrument panel. Disconnect the two trim springs on the left side. This could vary greatly depending how and what types of trim system is used.
On My LongEZ: I have the "compression" type springs and they are connected directly to the elevator trim bellhorn. If I compress the spring, I can then squeeze the hooks together on one end, then pull the hooks through the inside of the spring.
Adjust the trim for full "nose up". This will place tension on the upper spring.
Remove the bottom spring first. Get a helper to lift the elevator, this removes all the tension from the bottom spring and makes it easier to get out.
Remove the upper spring in a similiar fashion; Trim to full "nose down", and gently push down on the elevators while removing the top spring.
3) From the nose compartment, reach up inside and remove the two bolts that secure the canard.
In the photo, you can see the location of the mounting holes on both sides of the bulkhead. The Canards mounting tabs will hang down in front of this bulkhead and one bolt on each side will secure it to this bulkhead.
There should NOT be any washers between the tabs and the bulkhead,
Although most EZs were built with nut plates on the back, I have used regular self locking nuts and large area washers on the back of these bolts. (These are AN4 bolts)
When all the hardware is removed and the controls are disconnected;
4) You can do this by yourself;
In the following step, you will lift the leading edge and pull the canard forward. The back of the canard is held in place by two guide pins that insert into the canard. Often, these pins may get stuck in the canard. Not a big deal, simply pull them out of the canard and push them back into the fuselage with a tiny dab of epozy.
If the canard won't pop loose, goto the tip of the canard on rock it FORWARD/BACK about 1 inch, this should pop everything loose.
Facing the rear of the plane, Straddle the nose in front of the canard. With one hand gently raise the elevators, do NOT lift the canard, only the elevators. (this makes it so all the control bellhorn and counterweights don't get caught on anything when you slide the canard out )
With the other hand lift the leading edge of the canard about 1/2 inch. Pull the canard forward as you lift the front of the canard slightly. When the canard is released from the pins, it can be picked up and moved.
Reassemble in reverse order.
