Weheka,
Hard to believe anyone could seriously think that. Hopefully your opinion doesn't count for anything in this case.
Counts about as little as your opinion. Perhaps you could advise what your aeronautical experience is that enables you to come out with such profound statements.
In independent CAA approved and monitored flight tests, in the same type of aircraft, with the same load and C of G position, the aircraft was fully controllable in all flight conditions.
It may well have been, but it is not the load and C of G that is likely to have caused the problem. It was the position of the trim control at the commencement of the take off run, and at lift off, in conjunction with the aft c of g, which would have caused a major pitch up, and caused the pax to move even further aft and accentuate the problem until it became not recoverable.
Having been caught a few times myself, not remembering to reset the trim from the landing position to take off position, I am well aware ot the stick load that has to be overcome to keep the nose down at lift off. The FU24 has a large elevator trim tab, combined with a fully flying tail plane creating a very powerful force if not trimmed correctly.
