Rope & Rings & Fids
I offer several rope sizes and tow rings from TOST and Schweizer.
U.S. Towrope Regulations
FAR Part 91, section 91.309 states:
(3) The towline used has breaking strength not less than 80 percent of the maximum certificated operating weight of the glider or unpowered ultralight vehicle and not more than twice this operating weight. However, the towline used may have a breaking strength more than twice the maximum certificated operating weight of the glider or unpowered ultralight vehicle if -
(i) A safety link is installed at the point of attachment of the towline to the glider or unpowered ultralight vehicle with a breaking strength not less than 80 percent of the maximum certificated operating weight of the glider or unpowered ultralight vehicle and not greater than twice this operating weight;
(ii) A safety link is installed at the point of attachment of the towline to the towing aircraft with a breaking strength greater, but not more than 25 percent greater, than that of the safety link at the towed glider or unpowered ultralight vehicle end of the towline and not greater than twice the maximum certificated operating weight of the glider or unpowered ultralight vehicle;
Funny Photo of My Kids Helping Repair a Spool of Rope
The photo above shows my kids Adam, Elle and Sara and our cat Floyd helping me fix a 1000 foot spool of rope. The spool arrived with the spool broken in the middle. I certainly couldn't ship it to a customer that way. I thought it would be a fun family project to roll the rope off the broken spool, fix the spool and rewind it back onto the spool. I assumed it would be a 1/2 hour fun job for the kids and I. I was wrong - it took many hours of hard work to complete. Since the spool was broken in the middle it was very difficult to get the rope off the spool and near the end of the unwind process it became a tangled mess. The photo was taken after we succeeded in getting the rope un-tangled and started back onto the repaired spool. Sara was a real sport! 1000 feet of rope is a lot of rope to be coiled around you. She volunteered for the job and had fun with it for a while, but was very glad when the job was done. Unrolling the rope off of Sara and back onto the spool would seem to be an easy job, but a short way into the process the rope on the floor around her feet became very tangled. At one point she became tired and fell gently over onto her back on the rug. I offered her a cookie to go with a rest break. She looked extremely cute lying on her back, wrapped in rope, eating a cookie and laughing. We all had a good laugh. At that point I decided that the original plan was not working so I slipped Sara out from the center of the coil of rope. After many hours of pulling and untangling rope, we finally got it all back onto the repaired spool. It was a family adventure that we won't soon forget. In the end I had the manufacturer replace the spool anyway. I wouldn't want the same thing to happen to the customer if my duct tape repair didn't hold. But don't tell my kids I sent it back...
