Yikes. Hard to tell for sure from a grainy dash cam but something looks off about that Metro. Is it... upside down?

[PointyEngine]

Sure looks like a flipped bird...

Trying to find some more info but details are hard to find, anyone have a link with some more details?

I wonder if the gust locks were removed.

Here is a crisper video.

It almost reminds me of 1992's NewCal DHC Caribou crash at Gimli

I wonder if the gust locks were removed.

If its a metro, and the standard control locks are in place then they do not lock the elevator but they do lock the powers from being advanced higher than ground idle.

You mean like on the G-IV?

A mechanical interlock between the gust lock handle and the throttle levers restricts the movement of the throttle levers when the gust lock handle is in the ON position. According to Gulfstream, the interlock mechanism was intended to limit throttle lever movement to a throttle lever angle (TLA) of no greater than 6° during operation with the gust lock on. However, postaccident testing on nine in-service G-IV airplanes found that, with the gust lock handle in the ON position, the forward throttle lever movement that could be achieved on the G-IV was 3 to 4 times greater than the intended TLA of 6°.

During takeoff, the pilot-in-command (PIC) manually advanced the throttle levers, but the engine pressure ratio (EPR) did not reach the expected level due to the throttles contacting the gust lock/throttle lever interlock. The PIC did not immediately reject the takeoff; instead, he engaged the autothrottle, and the throttle levers moved slightly forward, which allowed the engines to attain an EPR value that approached (but never reached) the target setting.

Interpreting backwards from where the aircraft first appears, it appears that it is just finishing a roll to upside down, i.e. a VMC roll. Badly handled engine failure?

No....nothing like the GIV.

I don't think it actually went inverted. Looks more like knife edge. Happened right after takeoff, probably an engine failure that was mishandled.

First of all the powe levers get locked in beta so you wouldn't even get any forward thrust. Second, the rudder is also locked and pedals won't move. If the locks fail they spring load open so nothing is locked. 99.9% impossible to takeoff with locks on.
