b) Apply threadlock and tighten the bolts holding the trailing edge U-brackets, as
they are not easily accessible later, but not so tight as to prevent easy rotation
of the fittings by hand pressure.
2.5.2 Fitting the rear cabin uprights.
Refer to figure 27
a) Assemble the rear cabin uprights SKR6 to the main undercarriage cross-beam
SKR9 , using the second set of holes from the end.
Remember the bolt spacers on the two bolts at the bottom of SKR6 .
The bolts should all point rearwards through the main undercarriage
cross-beam
SKR6 .
b) Lift the upper triangle into position on the rear cabin uprights SKR6 and
temporarily secure with an 8mm diameter bolt.
c) Secure the bolts through the rear cabin uprights SKR6 and the upper cabin
triangle tubes SKR10 including the proper spacers etc..
This is easier now the upper cabin triangle is in place, although it is still
worth leaving all the accessible bolts loose until more of the fuselage is
assembled.
The 8mm bolts securing the rear cabin uprights SKR6 are fitted with
spacers and the nut must not be done up yet as there are more pieces
to fit to it.
2.6 Rear cabin frame bracing.
Figure 28 lower and upper ends of rear cabin frame diagonals.
a) Bolts and fittings for the SKR9 tube are packaged separately
– in a bag
marked ‘9’, Find these now.
b) Assemble the steel end pieces into the rear cabin frame diagonals SKR27 .
The one with the 8mm hole goes at the upper end and the one with the
6mm hole goes at the lower end.
