I have installed the Rivet Head conversion and I read someone saying that bullets don't go past the guide into and past the door frame. On mine they are going through the guide and through the door frame. Ok there. I also heard several post say to reach back and feel that the pin has gone through the door guide. If you have a full interior, like I do, you obviously can't do that because the area is covered. I have the door warning lights installed and I check religiously to be sure the light has gone off after the door is closed. I also will not let passengers close the door. I usually stay outside the plane until the passenger is buckled in and then I close the door. I can and would highly recommend the Rivet Head type of conversion. I think Steven DiNieri also has this type of conversion as well as Rivet Head. Boy the damage done to the latest door off incident surely gives you the incentive to double check that the doors are closed properly before takeoff.

How much does the door bow outward in flight. I am going flying in about 30 minutes and will check mine, but just wondering if any of the other flyers have tried to measure the flex. I have looked at it in flight before and do not remember any noticeable increased gap in the door. The reason I am interested is that I did cut my rods down to have the pins be just long enough to go through the AL blocks. With the tight fit of the doors, I do not think that a racking motion could pull the pin out of the block, outward flex of the door could have some affect.

Just to make a general comment, for good structural "retention" of the door, I feel the best set-up is for the door pins to pass completely through the opening frame on the fuselage. Of course, I'm basing this on the pictures I've seen so far. How does the warning light system "sense" full locking with the "blueprint" set-up for the door? Seems to me it would be a simple matter to add a couple micro-switches to the back side of the door frames so they light up (or better turn off a light) when the pins are fully engaged into the frames therefore indicating proper lock.

Not one single post by anyone on what that revised list might look like. Other than VAN being cautiously optimistic, Can any posters from SNF give us a teaser on what the new list might sound like before it hits us along the head with all claws extended? I know, I know the grounds are drying out and everyone has money to burn buying new toys. 25% of all GA flying aircraft are said to now be some form of the more than 29,000 (5,647 are VANS) Experimental built aircraft. The Genie is out of the bottle. Other than smoke and mirrors, will anyone shed some tangible light on this curiosity in a form we can get our arms around? Once it is out, in the Federal Register to trigger an NPRM, the fuse on the bomb will be lit. 280,000 attendees at SNF '08 and not a damn whisper. Wow! I understand Joe Bartels with his EVO Lancair prototype, VAN with the RV-12 prototype and Mikael Via of Glastar sat at the picnic table. I hear Hunger can make bad porridge taste better.

It is a big job to get down in the tunnel and disassemble the filter only to find that it is OK. Since filters clog progressively and not all at once, I measured the fuel flow by taking the fuel line off of the injector servo and connecting it to a hose that I drop the other end into the gas tank. I then turn on the boost pump and read the fuel flow. Mine started out at 42 gph and has not changed since I started flying. This gives me peace of mind without all the disassembly. If the flow drops below 40 gph I can then go and clean it. Though I would pass along this time saving tip.

We need a fix so that you can get in shut the door "thats it" No checking pins or reaching behind the seat etc etc. Ok so I am not convinced about this flexing yet as we cannot be sure the doors that have come off had the rear pins into the fuse (shut properly).

An unclosed door should not result in an major emergency in an un-pressurised a/c. This problem, if not corrected will be an accident waiting to happen. It is a bit like the Far Side cartoon the had a "Wings Off" button on the arm-rest of an airline passengers seat. The questions is not how to prevent the button being pushed but why it was there in the first pace. I know the risk can be mitigated by checking, with warning lights etc. But somewhere along the way, the failure chain will catch up with someone. Flying my Cherokee, part of the passenger brief is that they should un-latch the door in the event of an emergency so the door does not jam upon landing. I am reluctant to use the Auzzie fix as it may trap you in the a/c in the event of a crash. So rather than "fixes", what would be the "Gold Standard" solution? Inquiring minds need to know ....

After all the discussion, I am considering changing that and lengthening the rods and getting the pin to go through the frame. Have not really decided yet. Maybe I will have one of the ME's here give me an opinion about the strength of the AL block with the two bolts. My general feeling is that I am ok since those two bolts have a lot of strength in sheer.

That solution would require some major re engineering by Vans which is unlikely. In the short run, install a small handle on the aft part of the door to aid in closing from the inside on the ground. Then check your pins by feel or use the system. Do not shorten the pins so that they do not penetrate the door jambs; this is a recipe for disaster if the beveled tips hit anything where they will be stressed/abraded etc. Eventually they may be just short enough to slip out, given the flex of the door and the flex of the rear pushrod. IIRC it was bent slightly to match the curvature of the door. For 29 years I closed the passenger door on my Cardinal RG; not because it would depart the aircraft but the passenger could damage the door. The handle had a shear pin in it so that when the locking bar was pushed aft, it would shear if the bar was not properly positioned and was striking the door frame. I always locked the door to prevent my passenger from disabling the aircraft and creating a maintenance job for me. IIRC I posted a passenger warning placard in the 10 stating that my aircraft does not conform to certification standards. In my cases it meets or exceeds them but in the case of the doors I don't think it does. _____ From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of LES KEARNEY Sent: Friday, April 11, 2008 3:11 PM Subject: Re: RV10-List: Doors coming off Chris I have to say I agree with you.

If you let your engine get anywhere near their limits your rings will be toast and other bad things are likely. Keep CHT below 400 for all but the briefest periods, and take very positive corrective action if it ever gets close to 425.

It looked like the area around the hinges had little resin between the two surfaces. Also, the screw heads were flattened to bury them in resin so they would not turn when tightened from below. I would guess this was to create a beautiful look to the top of the door with no screw head showing. However, the shear force is absorbed at the large diameter of the screw head and the mating nut surface. Any grinding of the screw head removes area available for shear and its only shear that is securing the top of the door to the hinges. The deeper the screw head is set into the door the less holding strength is available from the fiberglass. So burying the screw heads cause two problems, and if they are over torqued cracking the fiberglass a third problem arises. Are others using this technique to make their doors beautiful? Look carefully at the rear door guide/protector/fuselage hole - it would appear that the rod never reached far beyond the teflon guide, otherwise the protector would be torn off.

Looks like he added both a small interior handle near the rear of the door and a secondary latch that seals the inside front side of the door. Tom H.
