6.3 Removal / Installation
6.3.1
General principles for work on control system
6.3.1.1
Push-pull rod adjustment
Type of maintenance: heavy
Authorization to perform:
LSA mechanic or A&P mechanic (Airframe and Power plant)
Tools needed:
wrench size 7/16 in
Set the push rods to the prescribed length before assembling, tighten the nuts slightly, and
do not secure them for the time being. It is necessary to keep the following principles:
Terminal thread must overlap the inspection hole in the push rod
Terminals of all push rods must be uniformly screwed for setting the neutral position
that serve for adjustment of control.
Grease bearings with lubricant grease before installing the push rods into airplane unless
otherwise stated by the bearing manufacturer. Do not grease nor rinse the bearings with
permanent filing that are covered by metal or plastic covers. Do not rinse bearings and
articulated joints with technical gasoline. Mechanically remove contaminated lubricant grease
carefully and refill the clean one.
6.3.1.2
Orientation of bolts and cotter pins
Put the bolts to the joint on the basis of “top-down” rule or “From the front to the back" with
regard to the flight direction. This rule decreases possibility of spontaneous bolt falling out of
the clamp joint in case that nut unlocking and falling out occurs in the course of operation.
Follow the same rule also in case of securing nuts by securing pins or by cotter pins, with the
exception of those cases when it is not possible to install the bolt for design or operation
limitation reasons.
6.3.1.3
Lubrication
At assembling parts grease al joints and friction surfaces (bolts, pins, and threads) after
mechanical or chemical cleaning by lubricant grease.
6.3.2
Control sticks removal
Type of maintenance: heavy
Authorization to perform:
LSA mechanic or A&P mechanic (Airframe and Power plant)
Tools needed:
wrench size 7/16 in, 3/8 in
wire nippers
Removal of the control sticks of manual control is shown on Fig. 6-7.
Disconnect push rod (1) of elevator control tube and fork on torque tube (2).
Disconnect push rods (3) of aileron control tubes on sticks (4).
Disconnect electric wire (5) for trim tab switches and PTT on the sticks.
Remove bolts (6) and bushings (7) from torque tube hinges (8) on the main center wing
spar (9).
Remove the control sticks assembly (10) from the cockpit.
