The multiple posts (by at least one) suggesting this crash may have resulted from tailplane icing reminds me of an earlier thread in which many seemed convinced tailplane icing was the likely culprit.
It was Colgan (Buffalo) in February 2009.
As I recall, the Colgan crew had been discussing tail plane icing on the way in towards Buffalo. Probably as a result of that discussion, the FO retracted the flaps without a command and without announcing her actions.
Then the CPT compounded it by overriding the stick pusher.
Tail plane icing is most likely to create a stabilizer stall with the flaps down.
We still do not know the flap position on this accident aircraft. We will probably have have to wait a bit to learn from the preliminary accident report.
Using the engine pitch moment to raise the nose is counter-intuitive in a nose low departure.
Unless you already have that trick in your bag of tricks, you are unlikely to use that technique when the chips are down.
