Aaron,
Good feedback. Can I ask if you reported the incident to Van's?
Cheers,

Chris,
I installed the Van's latch to plans, and have about 80 hours with it. Its
not hard to open from inside or outside, and the latch allows the door to
stay open a little on hot days.
The only concern I have to date is recently I got a little agressive on the
runup with just the safety latch engaged, and the door flew open. With this
happening on a ground runup with just the prop blast, I have serious doubts
it would hold if the main latch failed in flight. I suspect the door would
open just enough for the wind to grab it, flex it, and tear it off.
Now its possible that my install is not exactly like others, but after that
incident, I now assume the safety latch will be ineffective. I might start
to feel a little better if there are a few real examples of this latch
working in flight.
If I had to do it again, I would bite the bullet and buy one of the 3rd
party options being offered. Their secondary benefits are that there is
just one handle to move in an emergency, and they suck the door tight prior
to engaging the pins.
Just my 2 cents.
Aaron

Has anyone come up with a cool CNC machined replacement for the C1018 safety
latch that Vans provides for the door service bulletin?
Can I buy a couple?
I also wonder why the latch is installed in the center of the door, instead
of the front, near the handle. Maybe the idea is that the rear seat pax can
reach it there, with an unconscious co-pilot after a wreck. But the forward
location would allow the front seater to reach it without turning or
reaching behind them during normal ops or an emergency.
Also the fact that it is forward would maybe provide more security for it's
designed function, that is keeping the door from opening and flying off the
airplane. If the door is held in the center, due to the failure of the
primary latches, it could flex quite a bit, and maybe catch the wind enough
to tear off the airplane. If the safety latch is forward, then the small
partial opening in the front should not allow the air to get behind the
door, flex it, and create havoc.
Anyone deviate from the plans? I'm getting ready to cut some holes, and
would like a discussion on this.
Doors are kicking my #!**?

My guess if one contacted Vans they will state that it "was the first they have
heard of it"
Personally, I skipped the latch as I saw it as being worthless from the first look.
The latch assumes that the doors are going straight out/up which is not the
case. Grab the door and move it fore and aft and notice the amount of movement,
that is what happens when the door flies off it goes aft than off, that is
why the 3rd party concepts work well, they latch the door down and dont allow
the door to move out or back.
Anyone with the Vans latch will experience the same issue, better to have nothing
than false hope.
