A.  Position fairing to align support pins with holes in attach plates (Fig. 401).
B.  Move fairing aft to engage pins with attach plates.
C.  Secure fairing with washer and nut. Install cotter pin.
D.  Check that gaps at inboard edge and at aft end of fairing are 0.10 +0.05 inch and that mismatch does not exceed 0.03 inch. If gaps and mismatch are not within limits, adjust fairing (Ref Inboard Flap Track Fairing - A/T).
E.  If new fairing is being fitted:
(1)  
Jack airplane until all tires are clear of ground (Ref Jacking, Chapter 7).

(2)  
Check that electrical power is available.

(5)  
Remove gear ground lockpin from applicable main landing gear.

(6)  
Place landing ear control lever in UP position.

(7)  
Operate test bench to slowly retract gear.

(8)  
Check that gap between fairing and main gear shock strut door is 0.25 ±0.10 inch.

(9)  
Adjust fairing fore and aft to obtain proper gap.

NOTE: Gap limits at aft end of fairing must be maintained.

(10)

(2)  
If gaps and mismatch are not within limits determine amount of adjustment required, remove fairing and proceed as follows:

NOTE:  The following adjustments may be made individually or simultaneously, as necessary.

(3)  
Adjust fairing laterally and vertically as follows:

(a)  
Loosen clamping bolts (5) enough to allow movement of serrated plates (8). (See figure 501.)

(b)  
Position fairing flush with adjacent surfaces.

(c)  
Tighten bolts (5).

(4)  
Adjust fairing fore and aft as follows:

(a)  
Loosen nut (2) and checknuts (7). (See figure 501.)

(b)
