To Ronald: Yep. A good looking plane.
To Kevin:
Apparently I wasn't clear. I am an American and bound by FAA rules.
I was hoping someone knew of an unshielded alternative to the M41E that could keep the FAA happy.

 

The original Ercoupe didn't have spark plug eyebrows.   I like the lines.

“ Surely there is a plug that can be cross-referenced to it or a reasonable USA alternative to the overpriced Champion M41E.”

And has VALID STC or is an approved plug per the Continental type certificate data sheet!

You and your Canadian owner maintenance is going to get someone here into deep doo doo with our FAA.

I can point you to plug adapters that will enable the use of cheap automobile spark plugs. No STC, and NOT authorized.

What you can do with your Ercoupe would get ours grounded by the FAA.

A Canadian Maintenance disclaimer is a good idea.
As to spark plugs. The Ercoupe originally had short plugs and
no eyebrows. My 415C has no eyebrows and I wish to keep it that way.
Don't know what plugs were original to the 75hp. Surely there is a plug
that can be cross-referenced to it or a reasonable USA alternative to the
overpriced Champion M41E.
Anyone?

I have suggested that when he posts here, he makes a disclaimer that he is operating under a Canadian owner Maintenance program, similar to experimental, and what he can do with his aircraft would not be acceptable here in the states without a STC or a 337.

What he refuses to say is he is in Canada, and the Ercoupe is under owner Maintenace, almost like experimental, what he can do with his Ercoupe would get yours grounded by the FAA.
