FORCE DOES NOT EXCEED  
200 LBS AND DO NOT USE A HAMMER TO 
REMOVE THE BUSHINGS, THIS CAN CAUSE 
DAMAGE. 
 BEFORE YOU INSTALL THE C-CLAMP, MAKE 
SURE YOU INSTALL A SUPPORT BLOCK 
BETWEEN THE FITTINGS, SHIMS IN ALL 
GAPS AS REQUIRED TO AVOID BENDING 
AND DAMAGE FROM THE CLAMP FORCE. 
 OTHER METHOD THAN C-CLAMP COULD BE 
USED, PROVIDED LUGS ARE SUPPORTED 
AND LATERAL FORCE DOES NOT EXCEED 
200 LBS TO AVOID DAMAGE.

(d) Remove bushings (28), to disconnect the hinge box (19) from the forward 
attachment fitting.  Keep bushings if not damaged to re-install later.  Refer to 
Figures 3 and 6. 
CAUTION: HOLD THE FLAP HINGE BOX WHILE THE BOLTS ARE 
REMOVED.  IF THE FLAP HINGE BOX FALLS, IT WILL CAUSE 
DAMAGE TO THE FLAP HINGE BOX AND ATTACHED 
COMPONENTS. 
(e) Remove and keep the nuts (29), washer s (30) and (31), and bolts (32), to 
disconnect the hinge box (19) from the aft attachment fitting. 
(f) Remove bushings (33), to disconnec t the hinge box (19) from the aft 
attachment fitting.  Keep bushings if not damaged to re-install later.  Refer to 
Figure 3 and 6. 
CAUTION: MAKE SURE THERE IS SUFFICIENT CLEARANCE BETWEEN 
THE FLAP HINGE BOX AND AFT FAIRING TO AVOID DAMAGE 
TO THE AIRCRAFT STRUCTURE WHEN YOU LOWER THE FLAP 
HINGE BOX DOWNWARD FOR ACCESS. 
(2) Carefully pull the flap hinge box (19) downward to allow access to the forward 
lugs for the edge to edge distance inspection.
