The crash of Colgan3407 appears to maybe have been caused by a tail stall.
According to the NTSB on what they have heard so far from the cockpit voice recorder, they reported a severe pitch down once flaps were selected to 15 degrees.
From the NTSB brief:
Both the FDR and CVR are in excellent shape and have had an initial read in Washington.
The crew discussed significant ice buildup on the descent, airframe deice was selected on.
About one minute before the end of the recording, gear was selected down, 20 seconds later flaps 15 was selected, severe pitch and roll excursions started almost immediately after the flap selection.
The gear and flaps were raised and the recording ended soon afterward.
The briefing is being conducted by Steve Chealander, a former American Airlines captain and USAF Thunderbird.
That sucks.
And makes you think for sure. Because this is one pilot that KNOWS it could have been her. See here.
//it would appear it was far more simple than that. Ugh. I'll wait for the report to come out, but I have a feeling I can guess the gist of it.
