Van's has issued a service bulletin for their new door safety latch, which I installed 2 weeks ago. They have started shipping parts kits to those flying and those who have purchased finish kits. See attached link or go to Van's website.



The latch works very nicely and can also be used to pull the door inward while closing the door handle.

Thanks,

It looks very much like the Staniforth latch in the archives. I will take some pictures when I am out at the hangar tomorrow. My drawings are also at the hangar right now. With a little care, there should be no problem installing in a finished and painted door.

Attached are photos of the new door safety latch, which I think are self explanatory. It is my understanding that everyone with a finish kit will have their parts and drawings by the end of next week. The only thing I would consider changing is to increase the angle between the legs of the springs that you will fabricate. My personal preference would be for a stronger spring loading of the latch. I don't have a way to scan the large format drawings, but will try to photograph them and get them posted later today.

Who's going to be the first vendor to make the door safety latch kit parts

available with various stylistic improvements!!!  Come on you know that hook

looks so utilitarian... dare I say Dutch!   



What about warning lights, switches, buzzers... oh my!!



Tounge in cheek of course.

When you are inside of the plane and want to open the door, how do you open the latch?  Do you grab the edge of it.  What am I missing here?  Oh ya and you are on fire!

I for one would like something that would make that lever on the outside a little more streamlined and less ugly.  This should be fun with my already covered doors.

Hmmm



At least the Staniforth design had provision for opening on the interior. I

could see this getting jammed closed in the event of an accident - or at

least being very difficult to open.



What would really be nice would be the ability to open the door using the

main door handle and having this keep the door *slightly* ajar prior to an

off-field landing. On my Cherokee, part of the off field checklist is to

unlatch and unlock the door so it does not wedge shut in the event of an

accident.



Not knowing how tight this will hold the door, I am wondering if we are

trading on problem for another.

What about attaching a 'grab strap' to the inside door catch? It would 

serve for both opening and closing the doors from the inside?

I'm thinking of playing games with the color scheme. (Aka: alodine every other layer. Or alodine one layer darker than the other.)

 

 Or even anodizing with a color that complements the interior.

 

 I'm sure we'll have some machined versions soon though.

I saw this scottish influence personally. Anybody else see the 

resemblance? I'm going to call it the Nessie Latch.

I find it rather ludicrous to build an efficient airplane only to hang 

the handle and a speed brake on the outside of the door.  IMHO, it's a 

poor solution at best.

(I posted this at VAF, I also am not very impressed)



I am going to have to think about this SB before installing.   

 It would have been nice to talk with the whole community of RV-10 builders before launching this SB. I do not feel it is necessary and is just an extra device that if not installed properly will not function correctly I would suspect. If you drive to root cause on the door issue it comes down to people not installing the warning lights, and not properly completing their pre-flight. 

 

 I don't want to offend anyone that has had their door come off but I have heard many stories about the doors that have come off, especially the one that hit the horizontal stabilizer and there were many other factors involved with that incident. Most of them will admit that the door was never fully closed before taking off. All of them should have been prevented through proper preflight and checklists. 

 

 If the current system is installed correctly, the indicator lights installed, it is very unlikely and almost impossible to have a problem. The only way for the door to open is if you squeezed the interlock on the handle and opened the door. I know there are many RV-10's flying around with no indicator lights on the doors and I don't understand why. They work so great. On my doors if the pin moves 1/8" away from fully closed the lights come on. 

 

 My preflight includes the following: 

 -Confirm door handle has locked into place

 -Check all four corners for any obvious gap

 -Check door ajar light

 -Before takeoff, check all warning lights (includes the door ajar light)

 

 If the proximity sensors are installed correctly it is IMPOSSIBLE not to have each of the four pins in their proper spot. If one is caught outside the cabin (which has happened to me when passengers try to shut the door before I get there) the light is on and there is an obvious gap. 

 

 Another concern I read about is the handle not locking into place. If yours does not, take it apart and fix it. Once mine snaps into place it will not rotate and is very safe. 

 

 I may find that this is a great addition after I have played with someones door that has this new addition but I won't be adding this to my experimental plane anytime soon. I worry about emergencies and having someone on the outside who is trying to get me and my family out try to understand that you have to lift the little handle, push the button and rotate the handle. 

 

 I agree that the door can be improved but this is a very poor band-aid. I don't want to get flamed here, I just want new builders to understand that the doors are not unsafe and if installed correctly with the warning lights and properly locking handles they are safe. New builders have this perception that the doors need a 100% redesign, and I don't want anyone to be scared off.
