 A. Check of the Slat 1 Trailing Edge Backlash
 (1)
 For dimension X, at Tracks 1 thru 4, to check the slat knuckle bearings backlash:

 (a)
 Push the upper trailing edge of the slat down with a hand force of 25 kg (55.1155 lb). Put the load at each track position, at the trailing edge of the slat. Measure and write down the dimension X.

 (b)
 Pull the upper trailing edge of the slat up with a hand force of 25 kg (55.1155 lb). Put the load at each track position, at the trailing edge of the slat. Measure and write down the dimension X again.

 (c)
 Subtract the smaller dimension X from the larger dimension X to give you the surface-attachment spherical-bearing backlash. The difference between the two dimensions, that you wrote down, must be no more than 2.5 mm (0.0984 in.).

 (2)
 For dimension Y (tracks 2 and 3), to check the slat track drive system backlash:

 (a)
 Push the applicable track with a hand force of 25 kg (55.1155 lb) aft. Measure and write down the dimension Y.

 (b)
 Pull the applicable track with a hand force of 25 kg (55.1155 lb) forward. Measure and write down the dimension Y again.

 (c)
 Subtract the smaller dimension Y from the larger dimension Y to give you the rotary-actuator/transmission-shafts backlash. The difference between the two dimensions, that you wrote down, must be no more than 3.0 mm (0.1181 in.).
