I
don’t think the issue here is whether the IV can be flown safely. It
can. Those of us on the forum are proof of such (full disclosure – I fly
an ES-P). The issue is how much margin of error the plane offers when
the pilot makes a mistake. Even the best of us make mistakes.
Whether those mistakes kill us or not is a function of how many we make in a
row, how bad they are, and how much margin for error the plane gives us.
The first two are relatively independent of the plane you are flying.
The third is entirely dependent. A plane like the IV, with very narrow
margins of safety, will kill more pilots than a plane that has a much broader
set of safety margins because pilots are human and make
mistakes.
So,
in my opinion, relative to most other planes, the Lancair is less safe.
Let’s stop pretending otherwise. That is just part of the price we pay
for high performance. If you make a bad mistake, it is much more likely
to kill you, which is why it has such a poor safety record. This is not
the plane’s fault. Rather, it is because we as pilots can’t be perfect
all of the time.
