NOTE : When the points of the ambient temperature and the
____ underfloor temperature meet between the given lines of tension, then the correct tension reading will be calculated by linear extrapolation. (See the example on the graph). (Ref. Fig. 503/TASK 32-33-00-991-012)
(e) Operate the tensiometer. If necessary, adjust the turnbuckle body (9), until the tensiometer shows the same value as you find on the graph.

R R R R NOTE : If necessary, increase the cable tension to align the____ locking clips (10) and the turnbuckle body (9). Do not decrease the cable tension to align the locking clips (10) and the turnbuckle body (9).
(i) Remove the tensiometer.
(3) To adjust the cables (4) and (5):
(a) Do the procedure as for the cables (2) and (3).
(4) Remove the PIN, RIGGING - RUDDER CONTROL at position Pin 3.
(5) Remove the wedges from the GEAR GRAVITY EXTN operating handle (1).

(1) To let the cables and linkages become stable, operate the free-fall extension system through ten full cycles:
(a) For one full cycle, on the panel 110VU: - operate the GRAVITY GEAR EXTN handle three turns in a clockwise direction at a rate of one turn every five seconds
- operate the GRAVITY GEAR EXTN handle three turns in a counter-clockwise direction at a rate of one turn every five seconds.
(2) Lock the GEAR GRAVITY EXTN operating handle (1):
(a)
Put the handle (1) in the stowed position.
(b)
Put a wedge at each side of the handle (1), to keep it in position and prevent its movement.
