(x)
Hold the control column in this position for 30 seconds.
(y)
After 30 seconds, measure and write down the right elevator up travel while you hold the control column.
(z)
Make sure that the up travel is at least 29.08 inches
(738.6 mm) (View A-A, Fig. 505).
NOTE: If the right elevator does not have the necessary up
____ travel, do the procedure to adjust the first officer's aft quadrant stop.
(aa) Remove the pressure from the center hydraulic system (AMM 29-11-00/201). (ab) Put the C FLT CONTROL SHUTOFF switch on the P61 panel to the OFF position.
(ac) Open this circuit breaker on the P11 panel and attach
DO-NOT-CLOSE tags:
1) 11H18, FLT CONT SHUTOFF TAIL CTR
(ad) Remove the pressure from auxiliary pitot system No. 2
(AMM 34-11-00/201).
S 725-111
(2)
Do the steps that follow for the elevator full travel test with the outboard PCA supplied with power:
(a)
Remove the DO-NOT-CLOSE tags and close this circuit breaker on the P11 panel: 1) 11H28, FLT CONT SHUTOFF TAIL RIGHT
(b)
Put the R FLT CONTROL SHUTOFF switch on the P61 panel to the ON position.
WARNING: KEEP PERSONS AND EQUIPMENT AWAY FROM ALL CONTROL SURFACES
_______ WHEN HYDRAULIC POWER IS SUPPLIED. AILERONS, ELEVATORS, RUDDER, FLAPS, SLATS, SPOILERS, AND STABILIZER ARE FULLY POWERED SURFACES. INJURY TO PERSONS OR DAMAGE TO EQUIPMENT CAN OCCUR WHEN HYDRAULIC POWER IS SUPPLIED.
(c)
Pressurize the right hydraulic system (AMM 29-11-00/201).
(d)
Pressurize auxiliary pitot system No. 1 to between 0.60 to 0.65 psi (4.1 to 4.5 kPa) (159 to 165 knots) (AMM 34-11-00/201).
NOTE: Use airspeed values only when the static pressure on the
____ airspeed indicator is open to ambient pressure.
(e) Do the same procedure that was done for the inboard PCA to measure and write down the full up and down elevator travel.
NOTE: The necessary full up and down travel is the same as for
____ the inboard PCA supplied with power.

(4)
Do the steps that follow for the uniformity of powered travel between the PCAs test:
(a)
Compare the elevator travels that were written down for the full travel test with each PCA powered.
