Corrosion Preventive Compound - MIL-C-11796, Class 3
(2)
Sealant - BMS 5-95 (Ref 20-30-11)
B. Prepare for Adjustment
(1)
Provide electrical power.
(2)
Provide system A and B hydraulic power (Ref 27-61-0 MP).
(3)
Place speed brake control in UP position to raise spoilers.
(4)
Place FLT CONTROLS A switch on forward overhead panel to ON to pressurize trailing edge flaps.
(5)
Retract trailing edge flaps to full up position with jackscrew stops in contact.
(a)
Place flap control lever in FLAP UP detent.
(b)
Pull inboard on WFFA cable in wheel well until jackscrew stops contact.
(6)
Place speed brake control lever in DOWN position to lower spoilers.
C. Adjust Flight Spoiler
(1)
Check that spoiler to flap clearance is 0.03 (+ 0.10/-0.00) inch measured at point of minimum clearance. Rotate captain's control wheel clockwise to ensure that flight spoilers No. 2 and 3 are full down, or counterclockwise to ensure that flight spoilers No. 6 and 7 are full down (Fig. 501).
(2)
If spoiler to flap clearance is not within limits:
(a)
Provide access to spoiler actuator by either lowering flaps or opening applicable hinged trailing edge panel or by placing speed brake control lever in UP position to raise spoilers. Depressurize hydraulic systems A and B (Ref 27-61-0 MP).
WARNING: DO NOT PUT ANY PART OF BODY BETWEEN SPOILER AND WING UNLESS HYDRAULIC POWER IS REMOVED. SERIOUS INJURY CAN RESULT.
(b)
Break lockwire and loosen checknut on actuator rod end.
