E.  Should tension be incorrect, loosen the turnbuckle of the lower cable in the aft section of the fuse-lage and adjust the turnbuckle of the upper cable to obtain 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.
F.  Check safety of all turnbuckles and bolts.
G.  With the tension of the upper cable correct and the control wheel still forward, adjust the turn-buckle of the lower cable to obtain correct tension.
H.  Check the full travel of the control wheel with relation to the full travel of the stabilator to deter-mine that the stabilator contacts its stops before the control wheel contacts its stops. With the control wheel in the fore and aft positions, the travel distance from the joint where the stabilator contacts its stops and the control wheel contacts its stops should be approximately equal. Readjust turnbuckles if incorrect.
I.  Connect the assist springs to bulkhead sta. 156. (Refer to-Figure 27-18.)
J.  Install access panels and fin tip.
