[COUPERS] looking at spar caps

I was trying to make this point awhile back about spar caps.  I had four 1946 coupes, all four had bad spar caps.  I think they corrode from the inside out.  A couple of them looked OK from the outside, but when we took them apart, they  were corroded from the inside.  The best thing to do is put in the new spar caps and be done with it!  This looking at them all the time is not doing anything about the real problem.  Gene Martin from IL

 Fred Weick, the Coupe's designer, told me he never expected our planes to be flying more than about 10 years. Nothing else ever had up till the day he designed the Coupe, about 36 years after the first powered flight. He expected these planes to be recycled while we flew newer MUCH better designs. In his last years Fred repeatedly cautioned us about high speed cruise on bumpy days. It can produce, he said, high "g" force transient loads we shouldn't allow on our 55 year old planes. (And they were only 45 years old, mostly, when he was telling us that.) It's good to remember to slow down on bumpy days or climb up to 7,000-12,000 feet to be above the bumps for a long cruise.  ((Here's a 7146 prop grin from on high!))Ed Burkhead

     A while ago when we had this thread I learned alot about what 55 years
can do to an airplane. From that point on... in turbulence or cruddy weather,
the thought of something overlooked comes to mind. I guess others think so
too since John Wrights 'corrosion awareness'  speeches are so well recieved.
Thanks for bringing a topic that affects us one and all.
