maximum 2.0 mm (0.0787 in.) above wing surface (out of wind). (Ref. Fig. 804/TASK 57-41-37-991-016)
(55)
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).
(56)
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.
R (b) Get the correct thickness of spacer (123) (Ref. ASRM 574126).
(c)
Remove the bolts (52) and (64) and the pressure-relief panel (50).
(d)
Put the spacer (123) in position on the applicable landing.
(e)
Drill the applicable landing and the spacer (123) to a diameter R between 3.27 mm (0.1287 in.) and 3.35 mm (0.1318 in.) (Ref. ASRM R 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 R install the rivets (124) (Ref. ASRM 514211).
(h) Install the pressure-relief panel (50) with the bolts (52) and (64).

(57)
Measure the clearance between the D-nose skin and the leading edge of the pressure-relief panel (50). The clearance must be between 0.5 mm (0.0196 in.) and 4.5 mm (0.1771 in.).
(58)
Measure the clearance at the inboard and outboard edges of the pressure-relief panel (50). The clearance must be between 0.5 mm (0.0196 in.) and 5.5 mm (0.2165 in.).
(59)
At the trailing edge of the pressure-relief panel (50), measure the clearance between:
-
the wing-skin and the edge of the panel (that is parallel to the panel leading edge), the clearance must be between 0.5 mm (0.0196 in.) and 5.5 mm (0.2165 in.)
-
the wing-skin and the edge of the panel cut-outs (that are not parallel to the panel leading edge), the clearance must be between
0.5 mm (0.0196 in.) and 7.0 mm (0.2755 in.).
