 (e)
 Make sure that the harness (25) is not caught between:

 -
the key-hole slot positions on the intermediate fairing (17) and the wing skin

 -
the edge of the intermediate fairing (17) and the wing skin.

 (3)
 Install the rear fairing (16) as follows:

 (a)
 Make sure that the intermediate fairing (17) is correctly installed and pushed tightly against its stop.

 (g)
 Make sure that the:

 -forward end of the rear fairing (16) goes inside the intermediate fairing (17) (out-of-wind)
 -
harness (25) is not caught between the key-hole slot positions on the rear fairing (16) and the wing skin

 -
harness (25) is not caught between the edge of the rear fairing

 (16) and the wing skin.
 (h)
 Make sure that there is a clearance of 3.0 mm (0.1181 in.) to 4.0 mm (0.1574 in.) between the rear fairing (16) and the intermediate fairing (17). If necessary, cut and de-burr the overlap at the rear of the intermediate fairing (17) to get the correct dimension.

 (i)
 Install the bolt (15), the bush (14) and the nut (13). Tighten the bolt (15).

 (j)
 Fill the clearance between the rear fairing (16) and intermediate fairing (17) with SEALANTS (Material No. 09-016).

 (22) with the bolt (24), the washer (23) and the bush (18).
 2_ Loosely assemble the cover plate (22) complete with the front
 fairing (20) to the wing skin with the bolts (21).
 3_ Make sure that the front fairing (20) aligns with the
 intermediate fairing (17).
