"Rand company approve modifications to there design?" When I converted my KR from Retract to Fixed gear, I ordered the gear and plans from Rand Robinson. What comes next is an assumption. Since RR provided the material and plans/drawings for the conversion, I can't help but assume that they approve of the changes to the airframe. If this agrument is presented to your Assie Feds, perhaps they will agree. The arguement is even stronger if your aircraft is built per the RR plans.

The aft CofG limit is 302mm from the datum (WRLE) and if this is what I have to work with, it seriously limits the usable fuel. The header tank is 72 litres of which I can only burn off 28 litres before the CofG is outside the envelope!. Am I able too extend the aft CofG to 330mm as in some other KR-2s?. If not am I able to remove the retractable undercarriage and replace it with a fixed undercarriage which slopes slightly forward. I can then recalculate the E.W and Cof G without the engine, calculate the engine arm,and move the engine forward far enough to get the CofG right after max fuel burn off and not have the plane fall on it's nose. Seperate parts of this have been done by different builders but some were done under the VH experimental. Am I able to perform this sort of work under the 28 category? > Answer : As this A/C is a 101-28, and is built to a std eg FAR 23. > This means that the A/C must be maintained to this approved std. > If the mods you propose are out side the std to which your A/c was > built to, this will mean that you will not be able to modify this A/C. > My comment : Good grief, what next! Is there such a standard? Where can I find them?Can I do these modifications and still comply with these stds? Does the Rand company approve modifications to there design? Were can I find a list of these approved designs? Has anyone got some legal ideas? > _______________________________________ > to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net > please see other KRnet info at http://www.krnet.org/info.html >
