Strange one - spatial disorientation ? incapacitation ?
|
Wild ass guess: pressurization problem leading to incapacitation.

Does the TBM have a CVR ?
He was not talking on the radio so my wag would be an electrical failure of some kind or hit the master by mistake . Autopilot kicking off in the dark due to electrical issues would be a challenge for a full time pilot . I cannot imagine a part time pilot coping very well with an electrical issue at night . Add fatigue that is ignored by most private Operator guys and who knows ? |

Thanks for pointing out the correct time .
Electrical issues could have caused the windows to frost up on descent out of the flight levels , no attitude information . I have had several smoke and fire events in flight . Not easy to get deal with even when well rested and well drilled in Emergency procedures . |
NTSB News Release on the TBM 700 crash.

Some interesting information available particularly from Blancolirio on YouTube. The pilot lost radio contact and was way past the normal descent point when he reestablished communication. The controller trying to be helpful told him that he would be vectored over the airport at Buffalo with a turn back onto downwind (logically left 270 degrees to give room to descend). The pilot may not have understood this and as a private pilot flying a very high performance aircraft it is speculated he got behind the aircraft and lost situational awareness. In any case a very high rate of descent and speed developed along with a right turn in the direction of the downwind. The radar shows speeds well over 400 knots and it is possible he exceeded VNE and there was an ensuing breakup. This is just speculation, but it is one scenario that might fit the information available so far. I fly a high performance single (not nearly as high performance as a TBM) and the incredible amount of automation can make normal operation very simple. But once you get outside your comfort zone things can happen very quickly, particularly single pilot.
