preventative. Put the installation tools Figure 1 [30] and Figure 1 [31] in the ends of the long bolt
Figure 1 [11].
2.1.16
Install the forward bottom long bolt Figure 1 [11] and the torlon plates Figure 1 [13] and Figure 1 [14]
through the wing and fuselage fittings Figure 1 [10]. Use only hand force to install the long bolt
Figure 1 [11]. The torlon plates Figure 1 [13] and Figure 1 [14] have a different thickness, make sure
they are installed correctly as shown in the figure. Remove the installation tools Figure 1 [30] and
Figure 1 [31] from the long bolt Figure 1 [11]. If the long bolt Figure 1 [11] cannot be fully installed by
hand force, it is permitted to use the bolt removal tool Figure 1 [28] (with hand force only to turn the
knurled nut) to fully install the long bolt.
2.1.17
Remove all the unwanted corrosion preventive material from the wing and fuselage fittings.
2.1.18
Install the forward top bolt Figure 1 [1] that was removed during the wing removal, washer Figure 1 [2]
with the chamfer towards the bolt Figure 1 [1] head, washers Figure 1 [3] and the nut Figure 1 [6].
Torque the nut Figure 1 [6] to 50 Nm (443 lbf in). Remove the nut Figure 1 [6], washers Figure 1 [3],
Figure 1 [2] and the bolt Figure 1 [1]. Discard the used bolt Figure 1 [1].
Note
is a tension bolt which can only be torque tightened once. It is used in the above
step as a tool with a high torque value to correctly position the bushes that are not bonded. The bolt is
then removed and discarded.
2.1.19
Make sure the flange of the bushes have moved to touch the wing/fuselage fitting as shown by
Section A-A Fig. 1 .
2.1.20
Use Grease (Pt.No. P04-029) to lubricate the parts. Install the new forward top bolt Figure 1 [1],
washer Figure 1 [2] with the chamfer towards the bolt Figure 1 [1] head, washers Figure 1 [3] and the
new nut Figure 1 [6]. Torque the nut Figure 1 [6] to between 24 and 25,6 Nm (213 and 226 lbf in) plus
the nut friction torque.
2.1.21
Use Grease (Pt.No. P04-029) to lubricate the parts. Install the new forward bottom bolt Figure 1 [7],
washers Figure 1 [8] and Figure 1 [9], and the new nut Figure 1 [12]. Torque the nut Figure 1 [12] to
between 14,4 and 16,8 Nm (128 and 149 lbf in) plus the nut friction torque.
2.1.22
Use Grease (Pt.No. P04-029) to lubricate the parts. Install the new rear bottom bolt Figure 1 [21],
washer Figure 1 [17] with the chamfer towards the bolt Figure 1 [21] head, washers Figure 1 [16] and
the new nut Figure 1 [15]. Torque the nut Figure 1 [15] to between 14,4 and 16,8 Nm (128 and 149 lbf
in) plus the nut friction torque.
2.1.23
If a new wing is installed, release the lift force from the sling and carefully lower the jack that supports
the wing until the wing is not supported on the jack. If you install the wing that was removed, go to
Step 2.1.25.
2.1.24
Use a feeler gage to measure the gap between the fuselage frame 24 and the wing rear spar:
2.1.24.1
If the gap is less than 0,5 mm (0.02 in) go to Step 2.1.25.
2.1.24.2
If the gap is 0,5 mm (0.02 in) or more, install a Shim Figure 1 [26] between the fuselage frame 24 and
the wing rear spar.
2.1.25
Install the shim Figure 1 [26] if previously installed, and the washer Figure 1 [23] with the chamfer
towards the fitting. Use Grease (Pt.No. P04-029) to lubricate the nut. Install the new nut Figure 1 [22]
and torque to between 112 and 120 Nm (992 and 1062 lbf in) plus the nut friction torque. Make sure
the washer Figure 1 [23] does not turn when the nut Figure 1 [22] is torque tightened.
