An excellent description of the problem is found on page 5 of this accident report:

It is important to recognise that the negative g cut is a two stage phenomenon of lean cut possibly followed by rich cut, with the large amount of black smoke in the exhaust being symptomatic of over-fuelling (whether the engine actually cuts out or not is a function of the degree of over fuelling).
You can see this in the video; the smoke starts some time after the aeroplane passes 180ยบ roll angle. |
Yup I think that cinches it. I had forgotten that little tidbit form the movie. You can clearly see it just takes a second for it to be a problem.
