A. Pre-tension of the Cables
(1) You must put a pre-tension on the cable before you adjust it.
-In theory, the pre-tension time is 48 hours without movement of the aircraft. After this pre-tension time, the adjustment of the cable will stay correct.
-A minimum pre-tension time of 4 hours without movement of the aircraft is permitted. The adjustment of the cable will not stay correct for a long time. You must do the full pre-tension procedure when the aircraft stops for maintenance for a sufficiently long time.
NOTE : For a pre-tension time between 4 and 48 hours, the stability
____ of the adjustments is in proportion to the pre-tension time.
(2)
Apply a tension of 55 daN (123.6448 lbf) plus or minus 5 daN (11.2404 lbf) to the cable linkage.
(3)
The linkage must stay in this position for 48 hours.

- for the left cable: at 2542.9 mm (100.1142 in.) plus or minus 2 mm
(0.0787 in.)
(2) Release the tension on the cables.
