Here is a link to the final report of flight 3407:
Take some time to go though this report. There is a lot here. We can all learn something from this tragedy.
Our hearts go out to the families and friends of those involved in the Colgan accident. While none of us can bring these victims back, we can learn from what they left us and maybe help prevent a future accident.
As Regional Airline pilots we are more likely to run into tailplane icing because of the altitudes we fly at as well as the equipment we fly. It is an extremely dangerous condition. It is also difficult to detect and as we have discovered with flight 3407. It can be fatal when you think you have possible tailplane icing and don't.
There is some school of thought that tailplane icing should not be taught because it could possibly be confusing to pilots and could cause a pilot to misidentify a tail stall and do the exact opposite of what needs to be done in order to maintain positive control of an aircraft.
Some have even criticized NASA for making this video. I considered taking it down, but I'm going to leave it up for those that want to know about tailplane icing. I let you make your own decision on this matter.
Here is a NASA video that explains the effects of Tailplane Icing and what we as pilots can do to recover from Tailplane Icing.
