Roy, I always belived the stainless steel had to be added also for the gross weight increase STC.
If not, then there is a difference between both gross weight upgrades. However, the main thing is the elevator setting. And these are for both models the same. And when you compare a STC gross weight increased 415 C/D that already has the stainless steel addition with a 415/D ... no difference. Yet, one can be flown as Sport Pilot, the other not.

Not an inconsiderable piece of work. It is what convinced not to modify my ‘C’ to a ‘D’ some years ago. A decision I am now appreciate in light of the LSA rule.

So you can end up with 2 identical aircraft, one you can legally fly as Sport Pilot, the other not. Only one letter in the registration makes the difference. And even a 415-E does not differ from a 415 C/D when the latter has the split elevator installed. And yet one you can fly as a Sport Pilot, the other not. The planes are aerodynamically and structurally the same. Just a small difference in the registration... That is really too much bureaucracy to me..

It remained a Model C. (You can bet that is how the FAA would have treated it, should the pilot have been ramp checked.)

That is why I contacted the FAA. As my letter showed, the FAA still considers it a 415C based on the airworthiness certificate. I think the reqirements allowed on TCDS-787 are the modifications that are required, there is and was still a requirement to file and get approved form 8130-6 I believe that if someone has a Coupe that was converted to a 415D but still has a 415C or 415CD airworthiness certificate, it was never "legally" operated as a 415D. I believe there is a good case to present to the FAA.

Thanks also for the computer advice guys. Nick --- On Thu, 7/23/09, G. Davis <[email protected]> wrote: From: G.

I know this by experience, since I almost bought a D model that still was registered by the FAA as a 415-C. Probably no big deal, unless the 337 ever got filed or noticed by the FAA. Even the data plate said it was a C. But, the W&B showed 1400 gross wt. *Take care, and buyer beware. Gary Bing™ brings you maps, menus, and reviews organized in one place. Try it now.
