4. Check each control cable for the correct tension as given in Table V-I.
5. Should tension be incorrect,
loosen the turnbuckle of the lower cable in
the aft section of the fuselage and adjust the turnbuckle of the upper cable to ob-
tain correct tension.
Cable tension should be obtained with control wheel at the
one-quarter inch dimension from the stop and the stabilator contacting its stop.
6. Check safety of all turnbuckles and bolts.
7. With the tension of the upper cable correct and the control wheel still
forward, adjust the turnbuckle of the lower cable to obtain correct tension.
8. Check the full travel of the control wheel with relation to the full travel
of the stabilator to determine
that the stabilator
contacts its stops before the
control wheel contacts its stops. With the control wheel in the fore and aft posi-
tions, the travel distance from the point where the stabilator contacts its stops
and the controlwheel contacts its stops should be approximately equal. Readjust
turnbuckles if incorrect.
9. Reinstall access panels.
