Hmm,
There have been only 3 significant modifications from the factory.
Only one of those areas modified was due to problems on more than one
aircraft, and actually consisted of two modifications to the same
area. (warning lights and extra latch)
Your statement is a very broad brush allegation, with a small element
of truth...yes, all aircraft accidents are due to pilot error as well.
They shouldn't have challenged nature by attempting to fly in a man
made machine.
The fact that there have been at least a dozen door incidents is no
coincidence, and very unlikely that there was significant builder
error in that many aircraft. The fact that the door latching isn't
that positive, requires significant care by the pilot to ensure
adequate engagement is all evidence of poor design. No aircraft system
should require extra special attention on every flight like the
factory door design does.
It is better that new builders be aware of the potential safety issue
and the options available to reduce the risk than to tell them "just
build it" like some would do. Better to spend a bit extra time and
perhaps money on the doors than to have the airframe damaged, have to
spend a whole lot more time fixing it, assuming losing a door doesn't
precipitate a more serious accident. With awareness builders can make
informed choices and ensure they don't suffer the same problems of
those that led the way.

This can be onew OPINION but it factually is NOT TRUE. I would be willing
to bet a large sum that ALL the incidents with the RV10 doors were either
Pilot error OR Builder error.
I will leave it at that.................just wanted new RV10 builders
reading these post not to freak out and wonder what they must do different
in the building process.

One other observation. When the door is closed and latched, the full
circumference of the rear pin should be in contact with the metal of the
door frame or the metal door guide (after market). This may not be the case
depending on the accuracy of your location of the door latching mechanism
within the recessed box. In our case , it was not; hence we made new pins by
buying another appropriately typed and sized tube and slotting and drilling
one end and then installing the overly long pins. we retracted the pins and
test fit; then cut and beveled so that the retracted pin would just fit
inside the door frame. After several fittings, we were satisfied with the
fit. The retracted pins just fit inside the door frame and the extended
(closed) pins make full circumference contact with the complete hole in the
metal frame. Then after the doors are closed, before engine start, I feel
all four pin ends; before committing to flight they are felt again. I do not
use the light system because one builder who lost two doors, lost one of
them after installing the light system. I have suggested to Vans that the
pins should be supplied overly long by 1/2 inch and fitted by builder, but
have seen no change.
