CAUTION:_______ USE SUFFICIENT PADDING ON THE FORCE SCALE TO PREVENT DAMAGE TO
THE ELEVATOR SURFACE. USE A PAD THAT IS AT LEAST 5 INCHES
(12.7 cm) LONG AND HAS A WIDTH OF AT LEAST 5 INCHES (12.7 cm).
(4) Use the force scale to apply a 40 pound force +/- 5 pounds
(177.9 +/- 22.2 newtons) to the top of the elevator for 15 seconds or until the elevator movement stops. Apply this force on the elevator rib opposite the powered PCA and approximately 2 inches
(50.8 mm) forward of the elevator trailing edge.
NOTE: Use the longitudinal row of fasteners on the elevator skin to
____ identify the rib.
The right hydraulic system powers the outboard actuators, the left hydraulic system powers the center actuators, the center hydraulic system powers the inboard actuators.

(6)
Stop for 15 seconds or until the elevator movement stops.

CAUTION:_______ USE SUFFICIENT PADDING ON THE FORCE SCALE TO PREVENT DAMAGE TO
THE ELEVATOR SURFACE. USE A PAD THAT IS AT LEAST 5 INCHES
(127 mm) LONG AND HAS A WIDTH OF AT LEAST 5 INCHES (127 mm).##
(8) Use the force scale to slowly apply an 80 pound force +/- 10 pounds
(355.8 +/- 44.5 newtons) to the bottom of the elevator for 15 seconds or until the elevator movement stops. Apply this force along the elevator rib opposite the powered PCA and at the following locations:
OUTBOARD PCA approximately 2.0 inches (50.8mm) forward of the
elevator's trailing edge.
MIDDLE PCA approximately 4.75 inches (120.65mm) forward of the
elevator's trailing edge.
INBOARD PCA approximately 7.5 inches (190.5mm) forward of the
elevators's trailing edge.
NOTE: Use the longitudinal row of fasteners on the elevator skin
____ to indentify the rib. The RIGHT hydraulic system powers the OUTBOARD actuators. The LEFT hydraulic system powers the CENTER actuators. The CENTER hydraulic system powers the INBOARD actuators.

Do steps (4) thru (10) again (for the same PCA and side) to get a second freeplay measurement.
S 226-110
(12)
Make sure that the difference between the first and the second elevator freeplay measurement is not more than 0.040 inch (1.01 mm).
S 226-017
(13)
If the difference between the first and second elevator freeplay measurement is more than 0.040 inch (1.01 mm), then do these steps:
(a)
Do a check of the dial indicator installation.
(b)
Do the steps (4) thru (11) again until the difference between the two elevator freeplays is not more than 0.040 inch
(1.01 mm) .
