(b)  
Remove the control column lock from the first officer's control column.

 (c)  
Remove the force gage and control wheel adapter equipment.

 (d)  
Remove the pressure from the left, right, and center hydraulic systems, if it is not necessary (AMM 29-11-00/201).

 I.
Elevator Travel Limits Test

 S 725-110
 (1)  Do the steps that follow for the elevator full travel test with the inboard PCA supplied with power:
 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.
 (a)  
Pressurize the center hydraulic system (AMM 29-11-00/201).

 (b)  
Make sure that the pressure is removed from the left and right hydraulic systems (AMM 29-11-00/201).

 (c)  
Put the R and L FLT CONTROL SHUTOFF switches on the P61 panel to the OFF position.

 (d)  
Open these circuit breakers on the P11 panel and attach DO-NOT-CLOSE tags: 1) 11H17, FLT CONT SHUTOFF TAIL LEFT 2) 11H28, FLT CONT SHUTOFF TAIL RIGHT

 (e)  
Make sure that Dimension B on the stabilizer ballscrew actuator is 15.89 | 0.01 inches (403.6 | 0.3 mm) (Fig. 502).

 CAUTION: DO NOT LET THE PRESSURE GO ABOVE 4.75 PSI (32.8 KPA).
_______ (426 KNOTS). THIS WILL PREVENT DAMAGE TO THE FEEL COMPUTER. MAKE PRESSURE CHANGES SUCH THAT THE INDICATED RATE OF CLIMB (OR DESCENT) IS LESS THAN 5000 FEET PER MINUTE FOR THE STATIC SYSTEM AND 300 KNOTS PER MINUTE FOR THE PITOT SYSTEM.
 (f)  Pressurize auxiliary pitot system No. 2 to between 0.60 to 0.65 psig (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.

 (g) (h) (i) (j) (k)  Push the captain's control column forward until it touches the control column stop.Make sure the captain's aft quadrant touches the captain's aft quadrant stop (Fig. 505).Hold the control column in this position for 30 seconds.After 30 seconds, measure and write down the left elevator down travel while you hold the control column.Make sure that the down travel is at least 18.15 inches (461.0 mm) (View A-A, Fig. 505).
 NOTE:____ If the left elevator does not have the necessary down travel, do the procedure to adjust the captain's aft quadrant stop.
 (l) (m) (n) (o) (p)  Pull the captain's control column aft until it touches the control column stop.Make sure the captain's aft quadrant touches the captain's aft quadrant stop.Hold the control column in this position for 30 seconds.After 30 seconds, measure and write down the left elevator up travel while you hold the control column.Make sure that the up travel is at least 29.08 inches (738.6 mm) (View A-A, Fig. 505).
 NOTE:____ If the left elevator does not have the necessary up travel, do the procedure to adjust the captain's aft quadrant stop.
 (q) (r) (s) (t) (u)  Push the first officer's control column forward until it touches the control column stop.Make sure the first officer's aft quadrant touches the first officer's aft quadrant stop.Hold the control column in this position for 30 seconds.After 30 seconds, measure and write down the right elevator down travel while you hold the control column.Make sure that the down travel is at least 18.15 inches (461.0 mm) (View A-A, Fig. 505).
 NOTE:____ If the right elevator does not have the necessary down travel, do the procedure to adjust the first officer's aft quadrant stop.
