Lance,
I presume that the Fernandez skis you found are pretty old, as in fifteen plus years old??
If so, those were the old Fernandez (no 8001 model number-that's a different ski) retractable skis. Those are good skis on a Cub size airplane, but one of the problems they saw in southcentral Alaska with those skis is that, when installed on larger aircraft, they tended to be damaged with any rough use. If those have been on a 206.....guess what?
That company is no longer with us, and there is no direct support for those skis. That said, I think a good mechanic could do most of what you'd need done on them. I'd be skeptical of using those skis on a 180, particularly in North Dakota...due to rough snow.
There is a NEW ski type called the Rosti Fernandez 8001 ski, currently produced in Germany, that is similar in some ways to those older Fernandez skis. Many folks think these new skis are just a warmed over version of those older skis, and they do look a bit alike, superficially, but they are FAR different skis. Structures, materials, rigging, etc, are ALL very different. THOSE skis have been field approved on a Cessna 180 in Alaska.
With a set of Fernandez wheel skis, you WILL have to get a field approval. Good luck doing that with Fargo FSDO.
If I were going that route, I'd want to look at those skis VERY close, AND talk to mechanics/FSDO first to verify I could get them approved.
As to ski installations, get in touch with Jeff Faught in Bismark, if that's fairly close. Jeff works for Game and Fish, and does their maintenance. He's rigged them. Depending on where you're at, there are folks around with experience in that.
Let me know if you need contact info.
