George" George, I agree that we could use new manufactured wings for our Ercoupes, that would be a good solution to the on going spar problems. I think you will find that composite wings would be very hard to make that would be aerodynamically the same and that would directly attach to the current center section of the Ercoupe. Second, composite structures do not like prolonged exposure to sun light and many Ercoupe owners do not enjoy the luxury of a hangar. So what to do? It is possible to design (it has been done) a stressed skin direct replacement set of wings for the Ercoupe that is all sheet metal and lighter than our current wings. They are the same profile and would just bolt on with the same attachments. They look great and would be a big improvement to old tired wings. So why you might ask do we not have them? They would sell for around $ 6,000 a set and that is a lot of money unless you compare it to what Univar is asking for a new set today. The problem is that most owners will not spend about half what their Ercoupe is worth to fix a problem that they like to think they do not have (denial in many cases). This will not change until that FAA issues a comprehensive AD that will ground many Ercoupes and then people will want to purchase new wings. Right now it is a Catch - 22. We do not want to purchase the wings due to cost and no one wants to build them until there is a market for them. Watch the next few years for the rest of the story.
