Do a Check for Other Possible Causes

Make sure that the incorrect trim condition is not caused by a rigging problem or an out of tolerance system. Before you do the adjustment, make sure that these systems are in tolerance.
(a)
Make sure that each main wing tank has at least a 1000 pound
(453.6 Kg) fuel load. The fuel load must be divided equally (|5%) so that each main wing tank has the same fuel load.
(b) Make sure that the outboard-trailing-edge flaps are not out of tolerance. Make sure that the right outboard flap and the left outboard flap are symmetrical (use a tolerance of 0.14 degrees). Correct the rigging if it is necessary (Ref 27-51-00/501).
NOTE: The flaps must be up and pressurized for a minimum
____ of 30 seconds before you measure the flap angles.
(c) Make sure that the inboard trailing-edge flaps are in tolerance. Correct the rigging if it is necessary (Ref 27-51-02/501).
NOTE: The flaps must be up and pressurized for a minimum
____ of 30 seconds before you measure the flap angles.
(d) Make sure that the ailerons are in tolerance. Make sure the aileron trailing-edges align with the flap trailing-edges when the ailerons are in their neutral position (use a tolerance of
0.12 inch (3.0 mm) (Ref 27-11-00/501).
(e)
Make sure that the spoilers are in tolerance. Make sure that the .06 inch (1.5 mm) gap between the spoiler trailing edge and the flaps up position is correct. Correct the alignment if it is necessary (Ref 27-61-00/501).
(f)
Make sure that spoiler breakout does not occur before the control wheel has been turned clockwise or counterclockwise 8 degrees (Ref 27-61-00/501).

(g) Make sure that each elevator is aligned with its trailing-edge index plate (use a tolerance of 0.10 inch (2.54 mm)) when the stabilizer jackscrew dimension B is 15.89 | 0.01 inches
