Steevo's RV14a Build Log: Avionics

I've started my adventure to build a Van's Aircraft RV14a. For several years, I've been planning to build an Experimental (homebuilt) airplane - once retired.

But first, I needed to get my Pilot's License. (Kinda key !) So... first things first: I retired March 2014 from Caterpillar - and started flying lessons in the Summer of 2014. Soloed a day after Christmas, and got my Private July 2015. Shop set up, tools acquisition, and practise kits during Fall launched me into my build starting Dec 31, 2015 !

I've chosen to build the RV14a since it's about 10% larger than Van's prior models - so it fits my 6'4" frame well. Van's is well known for great value & outstanding flying qualities. It's been a no brainer decision for me. A tour of their facilities and demo flight in Oct 2013 clinched the deal. My wife - also a pilot - exclaimed after her demo flight "retire NOW so you can build one of these". The RV14a fits my mission of a good compromise between cross country & aerobatics. Plus...I fit, too.

So far, one month into building, it's been rewarding. Very challenging, but certainly a learning experience. The builder community is terrific - as is Van's tech support. I'm finished with the Vert Stab and Rudder (Jan 2016). So... with a 5 month delivery lead time, I've ordered the Quick Build Wings and Fuselage.

I hope this blog assists other new builders, just like several others have been valuable to me. Plus it will serve to document my build step by step. Please drop me a line via the "contact me" form on lower RH margin.

Update: April 2020 relocated to Wickenburg, Az to escape Illinois winters.

Avionics

Common Fuselage Harness ( 3 hrs )

Started installation of WH00125 Right Common Fuselage Harness per Sect 55. Vans provides no step by step instructions, only diagrams with general routing, snap bushings callouts, and a few details. I've reviewed other RV-14 builder logs searching for insights -which has helped. Many locations are very tight -- getting control stick wires/connector through tunnel side and ribs seems impossible. I'm going to have to talk to Vans prod support for tips ! Also discovered I need to detach elevator pushrod at bellcrank behind Flap support in order to pass connector rearward. Another aaarrrggghhh... Installing headphone & mike jacks stumped me concerning how to use stack of washers provided. Discovered Stein Air has this video on wiring these jacks, and end describes correct way to insure no metal contact (he notes 70% install incorrectly...leading to electrical ground loops = radio interference). Needed to enlarge forward hole to 7/16" to insure the plastic washer with shoulder fit properly ! Also found this video explaining how to avoid electrical ground loops.
