Step 1: Locate an ES-00301 above the lightening hole in the F-01207B-1 Baggage Bulkhead as shown in Figure 1. Match-Drill #30
the F-01207B-1.
Step 2: Rivet the ES-00301 to the F-01207B-1 as shown in Figure 1 and Figure 2, using the hardware called out in Figure 1.
Step 3: Measure and cut the Aft Pitot Line so it extends 24 in. [61.0 cm] forward of the forward-most plastic tie wrap installed in the
F-1280-L Left Side Skin in Section 10iS/U. This is now the F-00216 Garmin Static Line. Keep the remaining PT 1/4 OD Tube.
Step 4: Route the F-00216 forward through the lightening hole in the F-01207B-1 as shown in Figure 2, then insert the end of the
F-00216 into the FLF-00007 in the "Static" port of the GSU 25.
Step 5: Locate the F-00212 Garmin AOA Line (left coiled in the tailcone in Section 42MiS/U).
Step 6: Route the F-00212 forward through the lightening hole in the F-01207B-1 as shown in Figure 2, then insert the end of the
F-00212 into the FLF-00007 in the "AOA" port of the GSU 25.
Step 7: Measure, mark, and cut 103.5 in. [262.9 cm] of the remaining PT 1/4 OD Tube to fabricate the F-00214 Garmin Aft Pitot
line.
Step 8: Route one end of the F-00214 through the lightening hole in the F-01207B-1 as shown in Figure 2, then insert the end of
the F-00214 into the FLF-00007 in the "Pitot" port of the GSU 25.
Note: Ensure all Pitot-Static and AOA Lines are free from debris before connecting them to the
avionics.

Step 9: Loosely secure the F-00212, F-00214, and F-00216 to the ES-00301 using a tie wrap as shown in Figure 2. Leave the tie
wrap loose enough to allow the lines to slide through when the ADAHRS Baggage Floor Assembly is removed.
Step 10: Connect the 15-pin d-sub and 9-pin d-sub connectors labeled "ADAHRS" from the WH-00136 to the GSU 25 as shown in
Figure 2.
Step 11: Loosely secure the wires to the ES-00301 (installed in Section 42MiS/U) using a tie wrap as shown in Figure 2. Leave the
tie wrap loose enough to allow the wires to slide through when the ADAHRS Baggage Floor Assembly is removed.
Step 12: Check for F-00212, F-00214, F-00216, and wire bundle chafing or rubbing on the flight control cables, torque tube, or
surrounding structure. Reinstall the ADAHRS Baggage Floor Assembly as described in Section 38iS/U.
