4. Procedure
Subtask 27-64-00-440-051-B

A. Reactivation of the Spoiler Servo-Control
(1) If there is no plate with the 'O' and 'M' indications on the maintenance device (PRE GOODRICH VSB 31077-27-15):
(a) Put the servo-control in the Maintenance position:

CAUTION: DO NOT APPLY A HIGH TORQUE LOAD ON THE KEY SPOILER MAINTENANCE TOOL WHEN YOU SET THE SERVOCONTROL TO OPERATIONAL MODE OR MAINTENANCE MODE. IF YOU APPLY A HIGH TORQUE LOAD, IT CAN CAUSE DAMAGE TO THE TOOL AND/OR TO THE SERVOCONTROL.

1 Install the 98D27603002000 KEY-SPOILER MAINTENANCE98D27603002001 KEY-SPOILER MAINTENANCE (3) and turn it a quarter turn counterclockwise.

NOTE: The necessary torque to operate the maintenance device is 0.350 m.daN (30.97 lbf.in). If 0.350 m.daN (30.97 lbf.in) is not sufficient to turn the KEY-SPOILER MAINTENANCE, it is possible that the maintenance device is damaged. To prevent more damage to the maintenance device, remove the spoiler servo-control and send it back to the supplier for analysis.

a If you cannot turn the spoiler maintenance key, use the TOMMY BAR DIA 4 MM (0,157 IN) - METALLIC.
(b) Remove and discard the tie-wraps.
(c) Remove the CAP - BLANKING from the receptacle (1) and the connector (2).
(d) Connect the connector (2) to the receptacle (1) of the servo-control.
(e) Make sure that the spoiler is in the fully retracted position.
(f) Put the servo-control in the Operation position:

1 Turn the 98D27603002000 KEY-SPOILER MAINTENANCE98D27603002001 KEY-SPOILER MAINTENANCE (3) a quarter turn clockwise and remove it.

a If you cannot turn the spoiler maintenance key, use the TOMMY BAR DIA 4 MM (0,157 IN) - METALLIC.
(g) Make sure that the work area is clean and clear of tools and other items.
(h) Make sure that you cannot extend the spoiler:

CAUTION: MAKE SURE THAT NO SPOILER MAINTENANCE KEY STAYS ENGAGED IN THE MAINTENANCE DEVICE HOUSING. AERODYNAMIC FORCES WILL CAUSE UNWANTED MOVEMENT OF THE SPOILER IF THE MAINTENANCE KEY STAYS IN ITS HOUSING.

1 Gradually apply a manual force on the spoiler surface trailing-edge.
(2) If there is a plate with the 'O' and 'M' indications on the maintenance device (POST GOODRICH VSB 31077-27-15):
(a) Put the servo-control in the Maintenance position:

1 Install the 98D27603002000 KEY-SPOILER MAINTENANCE98D27603002001 KEY-SPOILER MAINTENANCE (3) and turn it a quarter turn counterclockwise to the 'M' position (Maintenance).

1 Turn the 98D27603002000 KEY-SPOILER MAINTENANCE98D27603002001 KEY-SPOILER MAINTENANCE (3) a quarter turn clockwise to the 'O' position (Operation) and remove it.

CAUTION: MAKE SURE THAT THE STOP OF THE HEXAGONAL-HEAD CONTROL SWITCH IS AGAINST THE LETTER 'O' ON THE HOUSING. IF IT IS AGAINST THE LETTER 'M', AERODYNAMIC FORCES WILL CAUSE UNWANTED MOVEMENT OF THE SPOILER AND POSSIBLE DAMAGE TO EQUIPMENT.

1 Gradually apply a manual force on the spoiler surface trailing-edge.

B. Preparation of the Test
(1) Remove the 98D27903500000 PIN-SIDE STICK LOCKING and the WARNING NOTICE(S) from each side stick assembly.
(2) Retract the flaps (Ref. AMM TASK 27-50-00-866-009).
(3) On the overhead panel, on FLT CTL panel 24VU, push the SEC 3 pushbutton switch (the OFF legend goes off).
