A.2.1.1 GMU 22 Mounting Bracket
An RV-7/9 GMU 22 Mounting Bracket Kit is available under Garmin part number 011-01796-00, see
Figure A-1. The aft deck was chosen as an installation location, as it provides a level pitch and roll
reference and acceptable separation from excessive magnetic disturbances. The mounting bracket is pre-
drilled to ensure proper alignment with the longitudinal (yaw) axis.

A.2.1.1.1 GMU 22 Mounting Bracket Installation Guidance
The RV-7/9 GMU 22 Mounting Bracket can be installed on the F-714 aft deck forward of the horizontal
stabilizer. Prior to installing the mounting bracket on the aft deck, the GMU 22 mounting plate
(115-00481-00) should be riveted to the mounting bracket. When riveting the mounting plate to the
bracket, ensure that the "Forward" arrow is pointing towards the front of the airplane and is parallel to the
longitudinal axis of the aircraft. As shown in
the bracket with the supplied AN426AD5-6 rivets.
NOTE
The GMU 22 mounting bracket outer dimensions are used for alignment. To minimize
inadvertent misalignment caused by edge alteration, it is recommended that the installer
NOT deburr the edges of the GMU 22 mounting bracket.
NOTE
After the GMU 22 mounting plate has been installed on the mounting bracket, the
following procedure should be followed to attach the mounting bracket to the F-714 aft
deck:
