  1. The 2007 CTLS fuel caps have turn and lock lever caps. The caps work well and can easily be adjusted by adjusting the bottom nylon lock nut. Early CTLS apparently had verticle vent tubes to create a small positive pressure in the tank because the vents at the wing tips did not work well. My 2007 has these verticle vents and the wing tip vents. I believe Flight Design may have later improved the fuel tank wing tip vents eliminating the need for the verticle pipe vents. You can replace the CTLS Fuel caps. They are SPRL caps. Aircraft Spruce and others offer these. Aircraft Spruce offers them as a set of cap and gas cap fitting that goes into the wing. They may sell separately, I do not know. But others do sell separately. You can also just replace the two O rings, the spring and the nylon nut. Aircraft Spruce sells this tune up kit If you have the verticle vent pipes, these will have to be moved to the new caps. I posted a photo earlier. The real problem is how Flight Design mounted the cap fittings in the wings. These are epoxied in without pins or screws/bolts. A sloppy lineman in New Orleans pried my left fitting out three years ago. There have been several reports on the forum of pilots loosing the whole system in flight. My concern was sucking fuel out, but the safety officer reported several years ago that missing caps create a negative pressure that prevents that tank from flowing. Watch the sight tubes! I have struggled for three years to get my left cap fitting to properly adhere to the wing. This joint is constantly bathed in fuel. I have recently purchased a new cap and fitting. I ruffed the fitting and base where it fits in wing. You need to use flexible epoxy as the wing flexes. This time I think I have it. But I have the parts if it comes out again. And I will check often. One more point and I will quit. Your CTLS fuel cap fitting can be loose and you will not know it if you do not wiggle by hand. Put the cap in closed and wiggle. See if the whole system is moving at the joint with the wing. If it moves at the epoxied joint, it will leak rain water here when the plane is outside. And it can detach. I hope I never post on CTLS fuel caps again. But I have gotten deep into them so call me if I can help Greg
  2. I have taxied on a flat front tire on a CTLS. VERY SLOWY Back to FBO after landing. No damage to tire. Torn stem on tube from under pressure and not the better tubes I use today.
  3. Posting this for those who may need to switch old vertical vent tubes to new SPRL gas caps on CTLS Roger and Tom were right. Surprise. The verticle vent tube does thread off. There is a nylon 6M-1 nut on the top side of molded cap and the same nut on the bottom side of molded cap. Screwing them together holds the vent tube in place. The tricky part is you can not grasp the lower nut or even see it well enough to know its a nut. You have to just keep tightening (clockwise) the top nut and it will eventually rotate the vent shaft out of the bottom nut. Drill the hole in the new cap and you are set to screw back together. Here is what the vent shafts and nuts look like without the molded cap. Hope this helps someone. Greg
  4. Photos of how the vent tube attaches. Thanks - Greg
  5. Thank you Roger and Tom I have a November 2007 CTLS. It has both the vents at the wing tips and the verticle post vent in the gas caps. The verticle post has a nut around the post just above the surface of the gas cap. The post is threaded at this point and the nut screws down to tighten the post. The post does not appear to be threaded below this point as it will spin freely once the nut is loosened, but the post will not pull out. There has to be a backing on the bottom side to allow the nut to torque against. There seems to be a rubber and plastic fitting around the bottom end of the post, but it is inside the molded cap so you can not get a grip on it. I am going to try to send photos I do not need this vent if the wing tip vents work??? Any suggestions on how to see if the wing tip vents work? Thanks much. Greg
  6. I want to replace my gas caps on CTLS. I ordered new caps from Aircraft Spruce. As expected they do not have the vertical vents added by flight design. My plan was to move the vents from the old caps. But I am having a problem removing the old vents from the old caps. I can loosen the nut on the upside of the cap. But the lower part of vent tube seems to be flaired in. Has anyone removed the vent tubes? Does anyone have a diagram? Will the fuel flow adequately without the vents? I appreciate any guidance. Thanks Greg
  7. Beautiful aircraft. Enjoy. Safe travels.
  8. 2007 CTLS. 487 hours
  9. Mainly the atmosphere of the restaurant being on the intercostal waterway and walkable from the airport Makes for a great lunch trip
  10. Gulfport and Gulf Shores both good stops. Gulfport towered with two runways. Town is full of great seafood Gulf Shores two runways. Lulu's one block from airport. Jimmy Buffet's sisters seafood restaurant If weather clears I will be landing Gulfport Early Wednesday. Safe travels. Greg
  11. I was taught to check the exhaust and do. What are the causes for the exhaust and/or muffler to crack?
  12. Andy Thanks
  13. Andy, if you don't mind, cann you identify the agent/broker and carrier? Thanks
  14. Andy and Dick. Did you put a backing inside the mushroom wall for support? If so, what? Thanks
