Exclamation RV10 Door came off shortly after take-off

The scenario is that a new RV10 owner has lost the pilot side door shortly after take-off. His fault and he accepted it, as he simply forgot to latch it properly. As far as I can find out, it was only the Vans spring loaded lock that was holding it.

I know of and has been involved in two other doors that came off locally and in both cases the doors could be repaired easily an re-installed. In both cases the plexi was not even scratched.

BUT

This RV10 was built in the USA and imported to South Africa in 2017 and it has done about 200 hours locally. As an AP (Approved Person) I was asked by the new owner to help with his broken door.

Looking at the door I could immediately see that there was NO ATTEMPT AT ALL to sand/scuff or roughen up (whatever you want to call it) mating surfaces and flanges. The material used to bond also does not look like cotton flox to me.

We now know that it will be a completely new LH door which will be expensive and a lot of hours. Taking into account that we will have to go and remove the wings etc. and trailer to my place to do the repair. I am also worrying about the RH door which will be the same if it has been done by the same builder.

The reason for this message is to bring it under the attention of ALL RV10 builders. Please guys stick to the building instructions which is very clear of what to use and how to build these doors. I believe they are critical parts and no shortcuts should be taken.

Below are some pictures. The first picture is of the piece that has remained on the cabin top. Comments are welcome and I really hope it will be seen by current builders.

Sorry to hear of your troubles. This is kind of to be expected with the current erector set level of kits available today. It allows a class of builder to complete a plane without the level of experience and skill found when the kits were more rudimentary and with drawings instead of instructions, though clear here that some don't even read those. Clearly many spend a lot of time here to learn the full breadth of skills needed, but suspect that many do not.

Really a shame to see these kinds of errors/omissions.

To late for a pre-buy inspection now, but I would suspect all phases of construction and want a thorough inspection of the whole plane prior to further flight. That door is representative of shoddy workmanship.

Thank you for the comments.
Dave how will a pre buy inspection on a painted door reveal this?

I am hoping for just bone builder to say thank you for the heads up because he has been on the wrong track.

It wouldn’t but there are other things that should be looked at closely. Maybe just an oops on the door but the plans are pretty specific on prep before bonding. There may be other slip-ups, or just shortcuts taken.

I no composite expert, but could you tap test the door edges to see if the bond is good? Obviously, you might not be able to identify poor prep work or improper materials, but you would (might?) be able to identify de-bonded areas.

+1 for..... tap test the door edges to hear if the bond is good. Obviously, you might not be able to identify poor prep work or improper materials, but you would be able to identify de-bonded areas.

Thank you guys - I will surely do a tap test on the other door.

I would just assume that the builder did the same thing on every important fiberglass joint.

Default Door hinge reinforcement

I'm just curious if the door reinforcement kit that Air Ward sells would have held the door in place?

For anyone that has installed this kit, what is your experience with it? Also, are the plates aluminum or stainless? How thick? I'm curious if this reinforcement would simply transfer the shear force to the cabin, which may not retain the door either, increasing damage further than just losing the door.

Does a door opening event in flight (and maybe on the ground too) always result in a liberation? If so, why hasn't Van's upgraded the door and mounting? I realize that's a question for Van's, but it's very interesting for me.
