Copy of STC SA4-1306

40-77 off Cessna 150s 5" wheel the 1 1/4" axel as the Piper axel is.. My brother Chuck has the fork on a inter cyl 614-738-8604 Dave he not going down to Cape Coral for a while. I was hoping he could take a set of seats down to you, could talk to him about that. Shipping from  NV. is going to be costly. I wiil get an idea tomorrow..

Still working on the dual nose fork. I've fabricated an axle to fit a 5" wheel and tire to help with the tail height. I'm waiting for a copy of the stc so I can get a field approval and give it a shot.

I see that document you referenced but also see they superseded it in 1992. I don’t know why anyone would want to do this and have a 6-600 tire on the nose. You will have a hard time getting the tail up. Univair has a similar looking nose conversion that you may have seen but overall the best way to convert to dual is to get the Ercoupe dual nose fork.

There is a reference to stc sa4-1306 for installation of a pa24 nose fork on an ercoupe in the documents section. I've scoured the faa and the web for a copy or the owner, no luck so far. As best I can tell it was developed prior to 1960. I've contacted one owner that had it documented, but it has since been changed. I've sent a letter to another owner, but no response yet. If this actually works, it will be very cool. I've already bought the piper nose fork and it definitely can work. If I had a copy of the stc, maybe I could see all of the unintended issues.
let's see what you guys and girls can find in your logs.
