Install Washer (Pt.No. 6107806-09) Figure 2 [5] and Knurled Nut (Pt.No. 6107806-08) Figure 2 [6] onto the
end of pin Figure 2 [2] and hand tighten. This action locates the jig in the correct fore-aft position.

Measure the gaps between the LH and RH Jig Assemblies Figure 3 [1] and the fuselage lugs on Frame 21
Figure 3 [2] and Frame 24 Figure 3 [3]. Check that the measurements are compliant with the information
contained in Fig. 3 and Table 6. Any deviation from these dimensions indicates local bending of lugs has
occurred.

3.4 Wing Alignment Checks
The following dimensional checks are to make sure that the fuselage lugs will allow the wings to align
correctly:
3.4.
1
Measure the gap between the face of the LH and RH Jig Assembly upper aft fitting Figure 3 [1] and the
corresponding face on the LH and RH Frame 24 upper lug Figure 3 [3]. The dimensions must be 1 mm ±0,5
mm. If the gap is outside of these limits, consult Pilatus Customer Support for further advice.
3.4.
2
Check the roll attitude of the LH and RH jigs at surfaces Figure 4 [5] and Figure 4 [6]. These surfaces must be
90 degrees ±0,05 degrees to the top of Frame 21.
3.4.
3
Check the longitudinal level of the LH and RH jigs between surfaces Figure 4 [1] and Figure 4 [4], and then
between surfaces Figure 4 [2] and Figure 4 [3] respectively. These surfaces must be within 0,125 degrees of
horizontal, and within 0,25 degrees of each other.
3.4.
4
Insert the Conical Centre Fittings (Pt.No. 6107806-20) Figure 4 [7], Figure 4 [8], Figure 4 [9] and Figure 4 [10]
into the holes on the lower side of each jig assembly.
