AC95 crash near Chino last night.

Are you seeing the pitch up on the 1000, because of the higher Vmo than the 690/840/980?

You might check with S-Tec-- that could be an installation issue. There are a number of parameters which are set in the installation process.

Regarding turbulence, I should add that I generally prefer to hand fly in moderate or greater turbulence. I'm just more comfortable letting the airplane float a bit rather than strictly trying to hold altitude and heading.

It’s software. We’ve installed more of these than I think all others combined at this point.

NTSB prelim is out. Nothing particularly new, other than it says that he was returning after completion of "recurrent" training, which seems a bit questionable? In any event, probably his first solo in the airplane.

I wonder if Commanders are more prone to that failing to bring the power up, leading to a stall/spin, than other aircraft?

In general, 331-powered aircraft are going to decelerate very rapidly with the power back, but I don't feel like we hear about MU-2s or Merlins having these issues... that said, the Merlin has a stick pusher, which would have maybe saved the day in this particular situation.

If you stall with autopilot(old school no alpha protection) engaged, it is pretty much guaranteed spin.

With Mits, I wonder if it's short and low aspect ratio wing is more prone to high sink rate, vs departure?

I would guess that spoilers have a better shot at high alpha rroll control than ailerons.

The low speed and high speed switching issues are common to several platforms.  I need to dig in to see what the resolutions have been. 

What is moderate turbulence these days? I think anything that makes a ripple in the coffee seems moderate to Delta airlines?

I believe the official definition of "moderate turbulence" and the one I use is if objects in the cabin are displaced.
