(b)
Slowly remove the force.

FOR AIRPLANES WITH GRAPHITE/COMPOSITE ELEVATOR TAB; make sure the sum of the two travel records is not more than 0.036 inch.
(8)
FOR AIRPLANES WITH ALUMINUM FIBERGLASS ELEVATOR TAB; make sure the sum of the two recorded travels is not more than 0.030 inch.
(9)
Remove the dial indicator.
(10)
Remove the mounting device.
(11)
Remove the device that you used to cause a blockage.
(12)
Repeat previous 11 steps for opposite tab.
E. Do these steps to make sure the axial play (inboard-outboard direction) of the tab is not more than 0.030 inch.
(1)
Hold the elevator tab around the trailing edge and move it outboard using hand pressure.
(2)
Use a feeler gage to measure the clearance between the elevator and the outboard end of the elevator tab and make a record of this clearance.
NOTE: It may be necessary to insert a flat metal filler block between the elevator and the elevator tab to help in this measurement.
(3)
Hold the elevator tab around the trailing edge and move it inboard using hand pressure.
(4)
Measure the clearance between the elevator and the outboard end of the elevator tab.
NOTE: The axial play is the difference in clearance measurements recorded in this step and the clearance recorded before.
(5)
Do the same check on the tab of the opposite elevator.
F. Put the airplane back to its usual condition.
(1) Release the pressure from the elevator control hydraulic systems A and B (AMM 27-31-0/201).
6. Hinged Flap - Inboard and Outboard
A. Position flap control lever to FLAPS DOWN to detent extend trailing edge flaps.
B. Apply approximately 5 pound upward force to hinged flap trailing edge. Check that hinged flap movement at end next to engine nacelle is not more than 0.250 inch.
NOTE: Hydraulic power is not required for this check.
7. Spoiler
A. Pressurize Hydraulic System A (AMM 27-51-0/201).
WARNING: KEEP PERSONS AND EQUIPMENT AWAY FROM ALL CONTROL SURFACES AND THE LANDING GEAR WHEN HYDRAULIC POWER IS SUPPLIED. THE AILERONS, ELEVATORS, RUDDER, FLAPS, SLATS, SPOILERS, STABILIZER, LANDING GEAR AND THRUST REVERSERS CAN MOVE QUICKLY WHEN SUPPLIED WITH POWER BY THE HYDRAULIC SYSTEMS. INJURIES TO PERSONS OR DAMAGE TO EQUIPMENT CAN OCCUR WHEN HYDRAULIC POWER IS SUPPLIED.
B. Put the flap control lever to the FLAPS DOWN (40-UNIT) detent to extend trailing edge flaps.
NOTE: You can do a check of the spoilers with hydraulic power on or off.

C. Release the pressure from Hydraulic System A (Ref 27-51-0, MP).
D. Do a check of the play of the spoilers No. 1, 2, 3, 6, 7 and 8:
CAUTION: USE SUFFICIENT PADDING ON THE FORCE SCALE TO PREVENT DAMAGE TO THE CONTROL SURFACE.
(1)
Push up with a force of approximately 21 pounds (the spoiler panel weight of 16 pounds plus 5 pounds pull force) on the spoiler trailing edge directly opposite the power control actuator and within 0.5 inch of the trailing edge of the spoiler panel.
(2)
Measure the play on the inboard edge of the spoiler not more than 1/2 inch from the trailing edge.
(3)
Make sure the spoiler play is not more than 0.10 inch.
E. Do a check of the play of the spoilers No. 4 and 5 (aluminum/fiberglass):
(1)
Push up with a force of approximately 33 pounds (the spoiler panel weight of 28 pounds plus 5 pounds pull force) at the midpoint between the two power control actuators of the spoiler, and within 0.5 inch of the panel trailing edge of the spoiler.
(2)
Measure the play on the inboard edge of the spoiler not more than 1/2 inch from the trailing edge.
(3)
Make sure the spoiler play is not more than 0.20 inch.
F. Do a check of the play of the spoilers No. 4 and 5 (graphic/composite):
(1)
Push up with a force of approximately 32 pounds (the spoiler panel weight of 27 pounds plus 5 pounds pull force) at the midpoint between the two spoiler power control actuators, and within 0.5 inch of the spoiler panel trailing edge.
(2)
Measure the play on the inboard edge of the spoiler not more than 1/2 inch from the trailing edge.
