I am just completing the empennage. kit on my 12iS. Looking way forward to page 7 of section 42PiS in the digital plans, I see an issue with installing the aft-most antenna in my eventual Garmin IFR package. How are you supposed to reach the area needed to drill the hole in flange f-1238-R and route the AV-532-L cable? Do you have to remove a skin panel? It appears to me that when using the Garmin G3X/IFR package, the cable and necessary parts should have been provided with the empennage kit and pre-routed prior to riveting the last skins. I think my 7 year old granddaughter is the only one in my family that could reach that area in a completed tailcone. ANY SUGGESTIONS APPRECIATED.
