Gmu 22 Mounting Bracket On The F714 Aft Deck - Garmin G3X Installation Manual

1. Draw a centerline down the middle of the F-714 aft deck.
2. Place the GMU 22 mounting bracket on the F-714 aft deck (see Figure A-2).
3. Slide the GMU 22 mounting bracket forward, ensuring the front edge is against the vertical portion
of the F-714 aft deck (see Figure A-2).
NOTE
It is vital that the front edge be squarely positioned against the flange. The GMU 22 rack
alignment points are based on the mount being perpendicular to the flange. The inner
edge should be aligned with the centerline on the fuselage.
4. SECURELY clamp the mounting bracket to the aft deck so that no movement occurs with the front
edge flush with the vertical portion of the F-714 aft deck.
5. Drill the six attach points with a #30 drill bit.
6. Rivet the mounting bracket to the aft deck using AN470AD4 or LP4-3 rivets. Alternatively, the
builder may elect to install the mounting bracket with non-ferrous fasteners (screws, washers, and
nuts).
