Dynon D-10A STC Approved for More Aircraft!

Dynon, the EAA, and the FAA announced last summer a revolutionary STC allowing installation of the (experimental category) Dynon D-10A EFIS in normal category aircraft. This is wonderful because it gives aircraft owners a relatively cheap way to update older aircraft with modern technology. It will make those aircraft safer, more reliable, and more useful.

The only part of the announcement that I didn't love was that my aircraft, a C-170A, wasn't included on the list of eligible aircraft. Thankfully, that problem has been rectified! The EAA just announced that several other aircraft models have been approved for this STC. You can get an official list on Dynon's website.

If you read the official list you'll notice that it includes a caveat in most cases: the aircraft must have been originally "equipped at the time of manufacture with a pneumatically driven primary attitude indicator." This might make some older aircraft ineligible.

I'm hoping that this STC is just the start of a larger movement. There are a lot of outstanding avionics only eligible for installation in experimental category aircraft right now. This technology has proven itself safe and reliable over thousands of flight hours in many varieties of aircraft. It feels like the FAA is warming to the idea that allowing normal category aircraft to take advantage of this technology will enhance aviation safety. I hope we see more STCs like this in the near future!

As a side note, I recently wrote about the FAA publishing a rule on 3rd class medical reform. This rule is great because it gives more pilots access to a wide range of aircraft models. Most of those aircraft are older and could use some refitting. An instrument like the D-10A is a perfect choice for that mission. It can make a very old airplane, like a C-150, into a trainer capable of preparing new students for flying in a world of technologically advanced aircraft...at very low cost. I think the combination of the BasicMed rule and STCs like this one have the potential to get a lot of older aircraft doing a lot more flying.
