JoeyMeatballs posted the link I was going to share. Just freakin' heartbreaking to read.
Combined with the one that went down last year, something is just not right there.

Just sit on your hands for more than 5 seconds!!!!! Dammit, NOTHING has to be done that fast. So, so frustrated right now.........

According to the report I saw this morning, they shut down the incorrect engine after about 10 seconds after the initial power loss.

IMO, experience is the only factor of judgment that can be measured objectively. The greater the experience database to draw on, the more likely judgment will find a match to compare the present situation and project a likely outcome.

I know, right?

The only checkride I ever came close to busting was my ATP. Almost killed the good engine by mistake. Fortunately, as my hand shot out to grab the (wrong) throttle, the thing you just said ("just sit on your hands for 5 seconds!") popped into my brain and I took a few moments, calmed down, and feathered the correct engine.

It's a darn shame this crew appears not to have had the same presence of mind.

Didn't Asiana have a check airman in the JS too? Weird trend.

I heard a report that apparently the #1 engine had recent Mx issues, so the crew may have been spring loaded to "expect" trouble from that one.

You never shut off a failed engine until you verify aircraft control after the affected thrust lever is moved to idle, why this isn't in the checklist, I have no idea.

It probably is in the checklist. I have never flow the ATR but I can assure you that their checklist or the Airlines checklist weights heavily on the manufacture checklist.

Sounds very much like this was a knee jerk reaction by one of the pilots and the other one was probably in shock. I could be wrong, of course, but I can almost guarantee you even their training probably says to do nothing until reaching a safe altitude. The reports will hopefully tell, sooner rather than later.

The only bold face needed:

Fly the airplane
Do not hurry
Silence the bell
