A36 crash

The fact that the plane had an estimated 25 hours since new indicates strongly
that it was the standard 25 hour inspection.

There's plenty of room for all of God's creatures. Right next to the
mashed potatoes.

Really? I didn't know there *was* a standard 25 hour inspection. Shows you
what I know about buying a new airplane.

Might that not contribute to the pilot's becming disoriented?

Anyway, that was just an example. It might have been the AI portion of the
display, instead.

If I had to bet, though, my money would be on simple spatial disorientation.
Until you've had it happen to you, you just don't know how easily you can
become completely fuzzled at night if you're not on your guard.

As I recall, there's not much to it - mainly check a bunch of stuff to make sure
it's still firmly attached and change the breakin oil out if that hasn't already
been done. There's another one due at 50 hours since new.

That would also explain why he was flying it elsewhere for the work. Bet that
was the dealer who sold him the plane.

You don't fly IFR do you? :-))
An AI, or HSI usually fails slowly. It just slowly rolls over to one
side or the other. If the pilot doesn't have a good scan technique he
just rolls with it.

I've flown that area and had the weather get really hazy just before
dark. Still VMC, but enough to start relying on the gauges.
I've also gotten caught down there when the visability went for good
to nil in a very short time. It wasn't real problem, but if you aren't
prepared it can scare you and getting disoriented is a strong likely
hood.

Must be a hell of a feeling for those folks, going from being thrilled with
the sale to this.

Yes, but probably not as much as you.

Agreed about the AI, disagree about the HSI.

Seems to me there's a BIG difference in the implications and dangers
between AI failing, which can cause loss of airplane ATTITUDE control,
and and HSI or DG failing, which could cause some loss of NAVIGATIONAL
awareness.

If your Horizontal Situation Indicator gradually turns to an incorrect
heading, do you think you might gradually, unknowingly, increase your
bank angle trying to "follow" it? Or maybe the CDI going off-scale
would induce you into a 60-degree bank trying to "catch it"? I think
not.

Losing a navigation instrument isn't a very good excuse to lose attitude
control even in IMC.

Good judgment is something else Munson didn't have. Showing off flaps-up
touch-and-goes in a Citation at night wasn't the smartest thing.
