"Has anyone thought of an LSAS failure?"
Doubtfull, the only LSAS failures I have ever encountered have been FCC boot failures. If it did fail all it would have done is provide full pilot elevator authority.
Fact: poor landing conditions.
Fact: poor landing.
Fact: aircraft crash from time to time.
I am with you on the over speculation. I believe it to be probable poor judgement mixed with horrible conditions. After the first bounce the nose down attitude reason will be determined from DFDR paramaters.
Did the landing pilot try to lower the angle of attack after he realized he flared too late too much?
Did he make the input after the hard landing in a desperate attempt to just get her on the ground?
Probably the first scenario mixed with the jar and force adding to the A.N.D. command. After the nose struck the first time they lost all control.
None the less, I believe the procedure to be to GA. in this scenario (bounce in windshear/crosswind) .#3 eng T.R. was deployed.
