Brief Description: Tunnel Access Panel, Control Panel Prep
Completed installation of tunnel access panel:
Dimpled the access panel reinforcing ring and the tunnel side for the AN426AD3-3.5 rivets. Had to remove the short 3/8" tubing connecting the fuel valve to the right fuel line bulkhead, in order to access the rear rivet holes.
Riveted the ring to the tunnel side using AN426AD3-3.5 rivets, with LP3-4 rivets along the bottom.
Since the fuel line was scraped up by the files while enlarging the access hole, I replaced the line using a piece of 3/8" tubing left over from earlier work.
Installed the access plate using the provided screws, and painted the cover and surrounding area to match the existing paint.
Cut the left side diagonal brace using tin snips. to allow room for the audio panel that was being blocked. Will install aluminum angle to provide the strength lost due to notching the brace.
Assembled the lower back trays provided by Aerotronics with the control panel and determined how they attach to the panel.
