NOTE 2 :
Aircraft S/N 129, 143, 144, 146 to 148, 150 to 152 and 156 are fitted with shims to get
this nominal gap. Should hinge fittings be installed with stress, remove shims and
apply this SB totally.
2) Remove horizontal stablizers – refer to Chapter 55- - -20- - -00 of the Maintenance
Manual.
3) Remove screws (3) and clamps (6).
4) Remove sealant beads (7) and unstick deicing tube (5) end of rib (8) to free outboard
hinge fitting (4).
5) Remove nuts (11), washers (10) and (13), bolts (12) and (14) and outboard hinge
fitting (4).
6) Perform a dye penetrant inspection to check for cracks on outboard hinge fitting (4)
and replace if cracked – refer to Chapter 55- - -10- - -00 of the Illustrated Parts Catalog
and Maintenance Manual.
7) If necessary, remove excess adhesive at rib (8)/end rib (15) interface ; let
over - - - thickness of approximately 0.008 in (0.2 mm) in order not to damage rib (8)
skin.
8) Apply Alodine 1200 and primer P23 on spar bare end.
9) If gap between pin (2) shoulder and ball joint (1) is between 0 and 0.039 in
(0 and 1 mm), perform the following operations
a) Position and secure outboard hinge fitting (4) with bolts (12) and washers (13).
b) Using feeler gages, measure gap between outboard hinge fitting (4) and end
rib (15) at bolt (14) attaching points.
c) If there is no gap, install bolts (14), washers (10) and nuts (11).
d) If there is a gap, define shim thickness.
NOTE :
Maximum thickness of shims permissible according to bolt (14) length is 0.071 in
(1.8 mm) and sum of shim thickness and gap at central hinge fitting should be
0.075 in (1.9 mm) maximum.
Example : Gap at central hinge fitting = 0.032 in (0.8 mm)
Existing gap at upper bolt = 0.051 in (1.3 mm)
Existing gap at lower bolt = 0.036 in (0.9 mm)
Calculation of shim thickness at upper bolt :
0.032 in (0.8 mm) + 0.051 in (1.3 mm) = 0.083 in (2.1 mm), above
0.075 in (1.9 mm) nominal gap.
Shim thickness = 0.075 in (1.9 mm) – 0.032 in (0.8 mm) = 0.043 in
(1.1 mm).
Calculation of shim thickness at lower bolt :
0.032 in (0.8 mm) + 0.036 in (0.9 mm) = 0.068 in (1.7 mm), below
0.075 in (1.9 mm) nominal gap.
Shim thickness = 0.036 in (0.9 mm).

h) Prepare a compound with FILLER ALU kit, P/N Z00.N4966056123.
i) Apply release agent on outboard hinge fitting (4).
j) Position shim washers (16) on outboard hinge fitting (4) bearing face and apply
FILLER ALU sufficiently to fill gap between outoard hinge fitting (4) total bearing
face and rib (8).
k) Position and secure outboard hinge fitting (4) with bolts (14) and (12),
washers (10) and (13) and nuts (11).
