__________
Subtask 27-80-00-941-063
A. Safety Precautions
(1)
Put the safety barriers in position.
(2)
Put a warning notice in the cockpit to tell persons not to operate the slat controls.
(3) Put the adjustable access platform in position below the work area. Subtask 27-80-00-860-067
B. Aircraft Maintenance Configuration WARNING : MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS ARE
_______ CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE.
(1)
Make sure that the slats are fully retracted (Ref. TASK 27-80-00-866-005).
(2)
Make sure that the TOOL-ZERO LOCKING, FLAP SLAT CTL LEVER (98D27803500001) is installed on the slat/flap control lever.

A. Permitted Aerodynamic Tolerances between the Slats 1 thru 5
(1) Check the slat end step tolerances as follows:
(a) Measure and write down the slat end step dimensions at points 1, 2, 3 and 4 for the slats 1 thru 5 (28 dimensions in total).

(b) Compare the 28 dimensions:
-23 of the 28 dimensions measured must be between the general tolerance limits given in the table J
-3 of the 28 dimensions measured can be between the general tolerance limits given in the table J +/- 0.5 mm (0.0196 in.)
-2 of the 28 dimensions measured can be between the general tolerance limits given in the table J +/- 1.5 mm (0.0590 in.).
(2)
Check the slat upper-trailing edge to 'D' nose step tolerances as follows:
(a)
For the slat 1, measure and write down the dimension X at points A, B, C, D and E (5 dimensions).
(b)
For the slats 2 thru 5, measure and write down the dimension X at points B, C and D (12 dimensions).
(c)
Compare the 17 dimensions X:
-14 of the 17 dimensions X must be between +/- 0.5 mm (0.0196 in.) of each other
-3 of the 17 dimensions X can be between +/- 1.0 mm (0.0393 in.) of each other.
(3)
Check the slat lower-trailing edge to 'D' nose step tolerances as follows:
(a)
For the slat 1, measure and write down the dimension Y at points F, G, H, J and K (5 dimensions).
(b)
For the slats 2 thru 5, measure and write down the dimension Y at points F, G and H (12 dimensions).
(c)
Compare the 17 dimensions Y:
-11 of the 17 dimensions Y must be between +/- 1.0 mm (0.0393 in.) of each other
