Someone had mentioned he was on the DL list 3 months, which is the amount of time they were holding guys back before being allowed to actually flow. I'm willing to give the guy the benefit of the doubt until unequivocally proven otherwise.

A senior sim instructor making a decent living with enough seniority to have solid control of his schedule would have plenty of reasons to decide not to take a flow to be junior for a few years, potentially commuting and unable to hold any weekends off.

So he didn't fail out of training, he chose to stay.

That's how I understood the story from the Ex endeavor guys I've flown with recently
That's exactly how I understand it

Short and sweet of it is approach speed was set appropriately at 149 knots per EDV guidance, power was at 64%, 175' airspeed got a bit slow at 144 knots, power remained the same, 150' airspeed spiked to 154 knots, PF brought power back to idle and remained there until touchdown. They lost the gust and the airspeed began to bleed off from there. Sink rate GPWS went off and airspeed decreased to 134 knots at touchdown where the right gear felt 3G's of force at 1098 FPM.

Sounds like a screw up all around. If going to idle is what it takes to arrest an increase in airspeed especially at 150', they should have went around. Or at the very least, only reduce power, but never go to idle and anticipate bringing it back in once the gust is lost. But go around would be the preferable and desirable course of action obviously vs trying to save it.

150' was plenty of time for the captain to intervene and either say something or take control. Both were at fault in this accident just going off the prelim.
Do we know power was idle? Also, where was the PM/PIC?! A sink rate and 10 knots slow should be an immediate GA.

43% N1 was the official engine speed it was pulled back to and stayed there all the way to touchdown. Either way a low power setting and never brought it back once the gust was lost.

Yes. But it didn't say it was idle. No use drawing conclusions that aren't in the report

I believe that’s about idle with icing on.

43% N1 has to be idle or extremily close.

4 seconds from threshold to touchdown is average 12.5fps. The vertical rate seems to increase as the nose drops closer to touchdown, and the right roll movement will increase the load on the landing gear.

I wouldn't be surprised if they find figures closer to 20fps on the RMLG at touchdown.
Looks like I was pretty damn close to actual values. 18.6fps Touchdown, add a little more because of the ongoing right roll so probably bang on the money at 20fps for the RMLG. And no flare whatsoever to arrest the sink, touchdown at 1 degrees pitch up, where it had been for the last few seconds of the flight. (per the TSB, normal is between 3 and 8 degrees).

For the CRJ guys, is VREF+5 really the correct speed? You don't add a gust factor?

According to the report Endeavor procedures are to set vref plus 5 plus 1/2 the gust factor not to exceed 10kts of gust additive.

Yes. Negligible power regardless, N1 is not linear to actual power, roughly 50% of your thrust comes after 80% N1.
