Checked the ELT and did the test. I turned off the master switch, got my portable receiver and pressed the test button on the ELT panel. I heard the ELT tone on 121.5 followed by a single beep. That indicated a good check and the ELT is OK. This test will have to be done every 3 mos. I caulked the GPS antenna, UAT antenna and the TED. Found a missing rivet on the underside which I squeezed. I added some data in the MX screen on the Skyview and cut off some of the L angle on the wing access panel that holds the camera. Lastly, I added 5 gallons of auto gas to both tanks. I now have 12 gallons in each.
