Welcome to Horizon Avionics!

We are a dedicated Avionics Shop and full-service A&P service located near the general-aviation ramp at McGhee Tyson (KTYS) airport in Knoxville Tennessee. We are a full-service Avionics shop, full aircraft maintenance (including annuals) and interior shop. Contact us at the phone number or email address below to see how we can serve your aircraft.

Please excuse our mess; we had a problem with our web site provider and we’re rebuilding our web site. We expect it to be fully back up to speed in a week or two.

Please contact us to schedule your ADS-B-out install. The January 1 2020 deadline is coming up FAST! If your plane isn’t 2020 compliant yet, don’t wait! (As of this writing, the FAA still has ADS-B rebates available, but hurry!)
