1. Empennage - Inspect complete surface of the vertical and X
horizontal stabilizers, of the elevator and rudder for damage
such as dents, cracks, holes and delamination.
2. Rudder Hinge, Elevator Hinge and Bellcranks - Check X
brackets and bellcranks for security of attachment and
corrosion. Inspect bearings for binding and excessive
play. Check correct safetying of the lower rudder pivot pin
with castellated nut and cotter pin.
3. Hinge Play and Control Surface Positioning - Verify clearance Ann.
between horizontal stabilizer and elevator horns and
clearance between vertical stabilizer and rudder horn is at
least 1 mm (0.04 in.). Check elevator hinge and rudder
hinge play max. allowed:
- Axial
± 0,30 mm (± 0.01 in.)
- Radial ± 0,30 mm (± 0.01 in.)
4. Elevator Control System - Measure the play in the elevator Ann.
control system with the control surface locked. Apply a force
of 50N (11.2 lbf) forwards and then backwards to the control
stick - the maximum play allowed on the top of the stick is
10 mm (0.4 in.) for both sides.
5. Rudder - Remove Rudder. Examine the elevator actuation 55-40-00 Ann.
assembly inside of the vertical stabilizer. Check for any
damage, for correct installation and function and for security
and wear. Inspect rudder hinge brackets, rudder yoke and
control cable thimble-eyes for security, conditions and wear.
Lubricate control cable thimble-eyes as required.
6. Rudder Rigging - Set rudder pedals in neutral position. 27-20-00 X
Verify the rudder and the nose landing gear are also in
neutral position. Set rudder pedals to fully left and then
to fully right. The rudder must hit the rudder travel stops
and the distance from rudder pedal to firewall must be
sufficiently for applying the pedal brake. Adjust position of
the rudder pedals by varying the length of nose wheel
steering tubes. Adjust rudder neutral position and control
cable tension by means of the turnbuckles in the cabin area.
