It is cost prohibitive, would cost you $200,000 to get a new spar designed and approved. And would it be any better, mine is still good after 50 years.Jim N87349 Pete Thomson wrote: ----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- Good morning David.

If we are to continue to keep these old birds airworthy, we need to take a pro-active approach. I'm sure that there would be some development cost, structural load analysis and such. At work, we have an outside DER review all of our structural modifications. Is it worth starting a dialog with him? Feed back, anybody? Coupers. I sent this last night to the coupers-tech list. I think it is interesting for every one. So here my posting again. Hartmut -------- Original Message -------- From: Hartmut <[EMAIL PROTECTED]> Subject: C-section & corrosion.
