Fwiw, my classic has lights yes, but that third mid door shoot bolt totally
solves
the issue, as it is not possible to close the door without engaging it, and
if it is engaged, the the rear shoot bolt is too.
A simpler solution is to add a static mid door pin, which would effectively do
the same job - ie, if its engaged the so is the rear, as it would pull the door
in and ensure alignment.

are not considered a good enough solution; why i have no idea; airbus boeing

aircraft... i thought about an alignment pin and cone assembly to ensure the
hatch is guided into correct position and that would require cutting into the
structure and somebody will still manage to somehow loose a door...

here good design is not an instant process; the idea may be instant yes,
and then it requires validation against a standard of defined presets; these are
the targets or kpi's to measure the outcome against through the development
process. in order to get to that outcome it's imperative to continue asking the
same two questions a) how did i arrive at this solusion/idea?, and b) can I
break this solution?... and you just keep going through back and forward until
validation is achieved and the set standard is met; and that's it.

has not been addressed; he broke the solution... clearly the doors flexing
too much is the root cause and real issue here... is it realistic to put an
AD out to have rigid carbon or ceramic doors fitted? Probably not due to the
cost... second distinction he made was the idea is reactionary... i believe John
was being polite; i'm not, it's a lego brick.

the best solution for many reasons, that's probably why boeing lockheed
and airbus use it; that's the solutiony going into my aircraft... And yes, as
with everything, as sure as the sun will shine and rain will fall, even if
fitted
to all europas, some idiot somewhere some day will still manage to screw
up and loose a door; 100% guaranteed.
