Yes that is right but there is the one big issue and that is that you must have the part manufactured to the drawing and "use all of the required process". In the case of many Ercoupe parts in the wing and spar that means fabricating them from soft aluminium and then having them heat treated (the process) and I have found that it is hard to find the details required to be assured that you have the required information. Some of the parts are from extrusions and with out the raw stock there is no practical way to make the part. I think that is the case on spar caps and it is why they cost so much to purchase. I would think very hard about the manufacture of parts that are not just simple sheet metal. We have in this list debated the simple issue of reattaching the wing attachment fittings when they have been removed. There is no simple way to do that. One owner had a tool made for several hundred dollars just to do his correctly. Others have suggested using bolts and that has some real concerns in it. The best thoughts I saw were the use of hiloc bolts after reaming the holes but there were still some question marks. In the end you have to bet your life on the part you have manufactured and accept the liability for it when you sell the aircraft. It can get to be a mess if you use a part that is not PMA or from the original manufacture produced under the type certificate (good used parts). I am sure you will do the right thing and I wish you the best of luck. Best regards, Vern ----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- Based on the letter that Harry produced for us, I can conlude that, if there is spar corrosion, I can have my A&P manufacture the part, provided we can do proper quality control (i.e. original blueprint info).... I have no idea yet if there is any corrosion on my plane, nor do I know what part or how much a replacement part (if req'd) would cost, I am just doing some research.. Thanks all, Matt N2864H "If a mechanic manufactured parts (e.g., wing ribs) for an owner, associated with a repair,would manufacture of the parts be considered maintenance or production of a part by the owner? Answer: It could be one or the other; in neither case, however, would there necessarily be an FAR violation. If it was concluded that the owner participated in controlling the design, manufacture, or quality of the part, he would be a producer, and the exception in FAR 21.303(b)(2)would apply" _________________________________________________________________ The new MSN 8: smart spam protection and 2 months FREE* http://join.msn.com/?page=features/junkmail ========================================================================== ==== To leave this forum go to: http://ercoupers.com/lists.htm Search the archives on http://escribe.com/aviation/coupers-tech/ ========================================================================== ==== To leave this forum go to: http://ercoupers.com/lists.htm Search the archives on http://escribe.com/aviation/coupers-tech/
