Re: C85 Engine up grade on n26658
Chuck, I think Terry has made some important points. I had my airplane reweighed after completing the repairs to damage it sustained in the wind storm a year ago December. It had been previously weighed seventeen years ago. I was not concerned about CG change but I wanted know the new empty weight. I always felt that my plane weighed more than previous weight and balance computations. Considering the changes that you have made I would be concerned about CG change and to a lesser extent empty weight gain.
I believe that the longer a plane is in service the more weight it will gain. Silt and water turned to mud inside wings,fuselage, etc. My plane gained 70 pounds or was always heavier than the weight and balance showed. Perhaps a mistake was made before? Perhaps not. At any rate I was shocked an dissapointed. It is what it is!! I have lost thirty pounds from my carcass in the last year so I do not notice any performance issues. Changes in density altitude is where I will notice it...There is a safety issue here. My useable weight has gone down... from close to 500 pounds to closer to 400 pounds.
The new weight and balance cost me $300. Very professioally done using a computer program with a (keep at home) manual showing equipment list and the process of weighing with diagrams and the same info in a small laminated binder with flip sheets to keep in the aircraft with different weight and balance scenerios and blanks that you can enter your own numbers and wipe off the laminate after. It also shows scenerios with skis versus wheels. If I still had my floats and if If I do again that will be added to the manual and flip binder.
Money well spent. It is professionaly done and It makes it easy for anyone to do a weight and balance quickly. If the FAA or a check pilot or who ever asks for my weight and balance I have it readily available.
