Chapter 6 REV. 0/02-15-02 AILERON CONTROLS 6-7 Lancair International Inc., Represented by Neico Aviation Inc., Copyright © 2000 , Redmond, OR 97756 The purpose of this hole is to check that the rod is sufficiently engaged. Using a thin wire try to insert through the hole. If you are able to insert the wire into the rod end there are not suffi- cient threads in rod end. When set, the check nut must be tight- ened. W A R N I N G (read and understand this) ( The situation shown is acceptable) Align skin using the factory installed cleco holes in leading edge. Weigh down with a couple of shot bags as necessary. Note: The dimensions are at the outboard end of the aileron. The aileron is flush with wing tip in neutral position.

Counterbalancing Ailerons The Legacy ailerons are 100% mass balanced. Initially install more lead than needed. After paint the excess will be removed for 100% mass balance. Note: Left side will require slightly more weight than the right side due to the trim system. Counter Balancing Ailerons Fig. 6:C:1 Trim Tab LEFT AILERON Note: The break is for the push-pull tube pas- sage. The premolded lead counterweight fits into the slot in the aileron leading edge. C 1. Prior to bonding the lead counterweights, insert the weights into the slots and add/remove lead as necessary. C 2. Temporary superglue the lead weights into place. Install aileron on wing and check for proper clearance through the travel range. Suggestion: Use a pointer as a reference for balancing (You can’t leave the level on the aileron when checking the balance.) C 5. After paint remove lead as required to achieve 100% balance. Note: All hardware including the trim system must be installed! UPPER WING SKIN Up 17° 0° Down -11° AFT SPAR C 3. Bond the counterweight in place with epoxy/flox. C 4. Secure the counter weight every 3” with a countersunk screw (MS24694-S56), washer(AN960-10L) and nylock nut (AN365-1032A). C 6. Install the aileron and check for proper clearance through the travel range. 1 3 . 0 ° Note: The above figure shows the aileron 100% mass balanced at the wing tip. Note: The above figure shows the aileron overbalanced. The counterweight should clear all structure by 1/8” min.

The trim tab must be safety wired prior to flight. S9 Servo Replaced with T4-5-T5 Servo. (Countersink the holes in the servo.) How the Trim System Works A trim tab deflection results in opposite deflection of control surface. Example: As the trim tab moves up, the (left) aileron moves down. This will cause the airplane to roll right. Neutral Fwd A/C Up Instructions for Adjusting the Aileron Trim Servo 1. Use a 12V battery to set the servo to center of travel (this is the neutral point). 2. Set the trim tab to neutral position (level). 3. Adjust the clevis accordingly.
