Joshua's RV-9A Project

Started the day by removing the panel after marking where the top of the subpanel cutout needed to be.  Filed the opening up to the line, and fabricated an angle to reinforce the left side of the cutout.  Panel back in, and marked the angle to drill a mounting hole for the SL-40 tray.  Primed and painted the angle and riveted it in place, and put in all the panel mounting screws.  It’s pretty solid, even without any attachment from panel to subpanel (except via the radio stack).

With the panel in, it’s time to get to work wiring.  The rest of the day was spent working on wiring the panel, both to itself and to the airframe.  There’s not really much to show, since it doesn’t look much different than it did yesterday.

• Drilled out the pitot heat indicator holes for LED holders and inserted some LEDs.  I was originally going to just Goop the LED’s in place, but this allows for the possibility of serviceability, at a minor aesthetic expense.
• All the wiring to the VP CU is complete, except for the backup alternator, since I don’t have that, nor do I know where it will be mounted.  The only “flying lead” at this point is for the ARINC converter, as I don’t know yet where that will mount, either.
• The power and grounds are run for the radio stack, and some other connections have been made, such as transponder encoder input and audio from EFIS 1.
• All antenna cables except for the ADS-B and GPS 2 (which is to feed the ADS-B)  have their panel ends terminated.
• All the switches are hooked up, as are the annunciator lights.
• The CO/SpO2 sensor’s serial connection is done.
• DB backshells are on the CO detector and both of the VP CU connectors.
• The PTT switches on the canopy decks are connected.
• Airframe autopilot wiring is routed, and a terminal block installed for the power and ground–a single power line feeds both servos plus the control head, so it needed to be split.
• A million zipties, give or take a few, have been installed and cut away.
• Scratched the panel on the upright between the EFIS screens while being (apparently) careless with a screwdriver.  Dang.  Will have to figure out how to best repaint that segment.

Need to look up a few things, and hopefully will get in a couple hours tomorrow between church commitments.

The only picture I managed to take today…
