PIPER CHEROKEE WARRIOR SERVICE MANUAL
3 . Secure the control column in the near forward position. On PA - 2 8-1 5 1 's, 1974 and 1975
m o dels, allow 0.25 ± 0.031 inch between the column and the stop bumper. For all other models, allow 0.25 +
0.12 -0.03 inch.
4. Check each control cable for the correct tension as given in Table V-II.
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 obtain correct tension. Cable tension should be
obtained with the 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 turn-
buckle 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 positions, the travel distance from the point where the stabilator contacts its stops and
the control wheel contacts its stops should approximately equal. Adjust turnbuckles if incorrect.
9. Install access panels.
d. Remove the airplane from jacks.

5. Tie the cables forward to prevent them from slipping back into the floor tunnel.
e. The trim control cables (8 and 9) may be removed by the following procedure:
1. Remove the rear seat bottom and the front seats, if desired.
2. Unfasten the carpet from the aft portion of the floor tunnel and lay it forward.
3. Remove the tunnel cover located between the trim control wheel and the spar cover by remov-
