Chris,
You sure base a lot of conclusions on one photo.
Lorn does not agree with you. (his
photo)
I do not agree with you.
And contrary to your innuendos, I have observed and
researched a lot more than you know.
. . . including my own set of test of control
forces and longitudinal stability on the LNC2.
And you fail to acknowledge that the pressure could
be from the gear being forced back up in the landing.
I detect that you check all possibilities when you
want to support yourself but are not as diligent otherwise.
If you are such an evangelist about the pump, why
haven't you made any progress with Lancair ? ?
Instead you keep trying to pick on me
because you don't like my position.
The only unfortunate thing here is that you still
don't want to let it go and let others make their own conclusions after
presenting your position.

Chris,
Why don't we just agree to disagree. I believe in
redundancy and it looks like you don't.
The pressure pulse you're talking about will
subside (glad you agree) and as it does, because the cylinder is only
partially extended, the cylinder will continues to extend, the low switch
will close again, and enable the pump to continue . . . No, the damage has NOT been done.
The only way the switch will stay open (the
pressure stays high) is if there is a physical obstruction preventing the from
moving down any further (like when it is full down).
Learn to live with the fact that you're not the
only one that knows a thing or two about airplanes.

Wolfgang,
It is unfortunate
that you do not have a Lancair and cannot go out and observe what we are
discussing. The extension failure has been observed by many. The pressure interaction is clearly
visible if one has pressure gauges installed in the panel. It caught your friend Lorn Olsen off
guard and he had a gear up landing because of it. Damage was definitely done. The photo he posted of his pressure
gauges after the landing very clearly showed the state of the hydraulics
during this failure mode. And no obstruction had to magically appear in
his lines to get it there. Your
module will not catch this failure mode.
One switch is open, one is closed, yet the gear is only partially
extended.
Advocating
not correcting a known problem is dangerous. Attempting to use a patch to correct a
problem is not redundancy. When the patch cannot detect a known failure mode
it provides a falls sense of security.
