Inboard TE Flap Adjustment

 S 215-017
 (1)  
Make sure that the TE flaps agree with the conditions that follow before you adjust the inboard TE flaps:

 (a)  
The outboard flaps are correctly adjusted with the outboard rigging bars (Ref 27-51-14).

 NOTE: If you cannot get the outboard flaps to agree with the
____ rigging adjustment (Ref 27-51-14), make sure that the lateral trim correction for the outboard flaps is below the limit (Ref 27-01-00). You must make allowance for rigging by lateral trim correction to get level flight for the airplane.
 (b)  
The left and right hand side of the outboard flaps are correctly sychronized to each other (Ref 27-51-14).

 (c)  
The inboard flap that you will not adjust must agree with the angular dimension (Fig. 504) and the vertical mismatch between the inboard and outboard flaps (Fig. 505).

 (2)
Remove the aft fairing for the inboard flap track (Ref 27-51-30).

 S 025-019

 (3)  
Remove the trunnion fairing door for the main landing gear (MLG) (Ref 32-12-10).
