The balloon on the left fuel tank held it's pressure through the night and the tank passed the leak test. I then repeated the procedure on the right tank and will check it tomorrow. I decided to mount the AOA box on the instrument panel support, above the ACS box. I manufactured mounts from aluminum angle and drilled for nutplates. The drilling, deburring, dimpling and riveting of nutplates was next. Then I primed the mounts.
