You know, the cost savings benefits of experimentals is a little over hyped. I have often thought about going to experimental to save on flying expenses, but when I do the math, it's really not that huge of a savings.
- The storage costs the same.
- The fuel costs the same.
- The insurance is the same, or even higher depending.
- If you didn't build it yourself, the annual costs the same.
- The airplanes themselves on the used market costs the same.
It's the repairs and upgrades that are cheaper. You can do the work yourself and save money on the labor. Otherwise paying for a repair, will cost the same in labor. The parts enjoy anywhere from a 10-40% discount over certified, depending on what it is. So, there are savings to be had.
But... how often do you actually have to do a repair, or plan upgrades?
Certified plane owners can find an IA to sign off on their own work. so if you really want to save on labor costs, this is an option. It still costs more than the experimental because you still have to hire an IA to sign off, but it probably does result in a 70-80% reduction in labor costs.
In the big scheme of aircraft ownership, going experimental is only going to save you maybe 10-15% over the life of ownership, if even that. No, the big allure to experimental is the shedding of much of the government oversight and red tape. In addition, E/AB brings many more choices of aircraft to the market. Not so much just to save money.
Oh and if you absolutely must have a brand new airplane, custom tailored to your specs, then there are huge savings to had in experimentals.
