 Put the pressure-relief panel (9) in position and install the bolts (10).

 (41)
 Apply release agent, SPECIAL MATERIALS (Material No. 05-064) to the trailing edge of the pressure-relief panel (30).

 (42)
 Put the pressure-relief panel (30) in position and install the bolts (28).

 (43)
 Measure the into/out of wind step tolerances of the pressure-relief panels (9) and (30) across the line of flight. These must be as follows:

 (a)
 For the panel leading edge:

 -
maximum 0.6 mm (0.0236 in.) above wing surface (into wind)

 -
maximum 1.2 mm (0.0472 in.) below wing surface (out of wind).

 (b)
 For the panel trailing edge:

 -
maximum 0.6 mm (0.0236 in.) below wing surface (into wind)

 -
maximum 2.0 mm (0.0787 in.) above wing surface (out of wind).

 (44) Measure the step tolerances of the pressure-relief panel ends across the line of flight. These must be as follows:
 (a) For the panel ends:
 -
maximum 2.0 mm (0.0787 in.) above or below the adjacent panel end (DIM X)

 -
maximum 2.0 mm (0.0787 in.) above or below the adjacent wing surface (DIM Y).

 If an into/out of wind step or an end step is not in tolerance, continue as follows:

 (a)
 Calculate the necessary thickness of the spacer (123) required to make the step correct.

 (b)
 Get the correct thickness of spacer (123) (Ref. SRM 574126).

 (c)
 Remove the applicable bolts (10) and/or (28) and the applicable pressure-relief panel (9) and/or (30).

 (d)
 Put the spacer (123) in position on the applicable landing.

 (e)
 Drill the applicable landing and the spacer (123) to a diameter between 3.27 mm (0.1287 in.) and 3.35 mm (0.1318 in.) (Ref. SRM 514411).

 (f)
 Remove the sharp edges from the applicable landing and the spacer (123).

 (g)
 Put the spacer (123) in position on the applicable landing and install the rivets (124) (Ref. SRM 514211).

 (h)
 Install the applicable pressure-relief panel (9) and/or (30) with the bolts (10) and/or (28).

 (i)
 Do again step (41) and step (42).

 (46)
 Measure the gap between the D-nose skin and the leading edges of the pressure-relief panels (9) and (30). The gap must be between 0.5 mm (0.0196 in.) and 4.5 mm (0.1771 in.).

 (47)
 Measure the gap at the inboard and outboard edges of the pressure-relief panels (9) and (30). The gap must be between 0.5 mm (0.0196 in.) and 5.5 mm (0.2165 in.).

 (48)
 At the trailing edges of the pressure-relief panels (9) and (30), measure:

 -the gap between the wing-skin and the edges of the panels. The gap must not be less than 0.5 mm (0.0196 in.).
