Stressed Skin Repair Question
Hi,
I'm looking for input on the best way to layout a repair of some "hangar rash" on the tail boom of my Taylor Coot amphibian project. The damaged area is on a 10in diameter .065in 6061 T6 tube that serves as the tail boom on this aircraft. The part was dropped and sustained a crease roughly perpendicular (but not quite) to the length of the tube. I have removed the displaced material and now have an opening 4.1in long and 1.1in wide. Since I'll be joining two sheets of .065, I've selected -6 rivets. I also realize that I'll need to slip roll the patch. I'm now trying to apply the guidance for stressed skin repairs found in AC 4313-1B around paragraph 4-58 figure 4-16 and tables 4-9 through 4-11 (note that there is apparently no table for 6061 T6). Here is a link to an image showing the current state to the repair: http://rilinterface.com/Cootnest/Ima...e/DSCN0997.jpg I'd love to get folks' input on how best to lay out the repair for this. Thanks! Russ http://rilinterface.com/cootnest |
