Default my mistake

You are correct, the guide blocks are not delrin, they are soft and easy to cut.

Default thanks

Thanks, I didn't want builders thinking I sell the soft stuff that Vans supplies.
I am considering changing out the flap bearings that are made from UHMW in the fuselage with Nylon pieces. I noticed some of the slop in the flap is due to the ovalling of these pieces. Nylon is a lot harder and is very impact resistant.

Unless you builders are now stamping the serial numbers on the door like Piper or GM might do, I have a feeling this is not a -10.

I have the iflyrv10 door pins (steel) and receiving blocks (billet aluminum). I also close the doors from the outside as part of my walkaround.

As another sample point, my doors do not require pulling on the rear. I can pull the lock handle with a gentle pull, and it will latch fine using the Al pins and guide blocks and mcmastercarr seals.

If i don't pull a bit, then the rear pin will hit the flat part of the guide block and not allow engagement of either pin. The only time I had the rear pin out and forward pin in, was when I had a power cord running through the door in the back, and THAT did cause the rear pin to latch outside of the fuse.

However, what I don't know is:

1. With the engine started and at idle, can i still close the front door properly? I don't know what will happen to the door.

2. What happens to the door in an up position at idle and taxi speeds?

Smile Easy swap of pin blocks

FYI: If this has convinced anyone to ditch their plastic plates and you want a quick and easy solution for swapping only the blocks, AirCrafters sells a set of four plates made of 2024.

The iflyRV10 kit looks nice too. I guess it depends on how much one wants to alter.

Default Couple of comments....

I am pretty sure that the guide blocks supplied in RV-10 finish kits are now made of Delrin (and I believe they have been for a couple of years).

I will not enter an argument of whether the RV-10 should have a different door design or not, but will suggest that at some point a pilot needs to take responsibility for his/her actions while flying an airplane.

Check lists are for helping us overcome our nature of not being perfect.

If we should redesign the door system on an RV-10 because of the high likelihood that there will always be pilots that will take-off without a door being properly latched...

Then we should also redesign the fuel system for all RV models (except the fuselage tank RV-3's) so that it is not possible for a pilot to take-off with an empty (or nearly so) tank selected or with the selector in the off position...

And, we should redesign the trim systems so that you can't start the engine without properly setting the pitch trim for take-off...

And, we should.... well, you get the idea.

I am not at all saying that improvements should not be made if safety of flight issues are discovered (which has been done countless times with different RV models over the years), but there is a practical limit to that.

At some point, the pilot has to get serious about his/her level of responsibility for completing a safe flight, when flying an airplane.

Then why did Vans try to fix it? That goes against Vans making a Service Bulletin that "fixes" the problem. Then when they do, they make a two handed operation.

Re-read the last two lines of my post

Van's made a contribution towards trying to make RV-10 pilots safer (which they had already done by supplying an indicator system), it was never considered a fix for the problem. No one can force pilots to use a checklist, any more than they can stop them from running out of fuel.
You can argue this issue all you want but it comes down to a very simple fact. If RV-10 pilots install the door indicator system and adjust it as specified, and (with the memory aid of a check list) check the indicator system before they take-off, doors would not be departing from RV-10's.

RV-10 pilots should make their contribution, and be responsible pilots regarding check list use and verification of items on the check list.

If a builder has chosen to install the door unsafe indicators at a location that is difficult to see (No excuse,the builder is the panel designer, the plans don't specify specifically where to locate them), then install a different indicator that is easy for you to see.

(I have seen no evidence that making the passive safety latch a two handed operation is a bad thing)

Default improvements

I like the magnetic proximity sensors and have them installed. This was a great Service Letter and it was practical.
