I finished drilling the holes for the nutplates that will mount the left mid-cabin covers, then installed the two #8 nutplates in the aft fuel selector attach angle.

Next, I drilled a 7/8" hole in the bulkhead just behind the rear passenger's right elbow, and test-installed a 12V power outlet. The rear-seater will be able to use this for a GPS, a gooseneck map light, an iPod, or whatever. [Later superseded.]

While I was back there, I drilled two 3/8" holes on the bulkhead just forward of this for the rear seater's headset jacks.

Finally, I scouted for the ideal location for the overboard drain hole for the smoke system. The most likely location will be on the belly, under the forward edge of the rear baggage compartment floor.
