Savoia,
nice job on the table/matrix.
Last week I was in Liege, Belgium. There was the 31250, owned by the Dutch police for a repair on the crosstube of the collective. It seems the crosstube was fitting wrongly in the factory (Vergiate).
The tube didn't fit in the brackets and was with excessief forces put in place. This concluded that lots of forces where needed to move the collective. The force needed where that high that the AP wasn't able to maintain altitude.
Something to keep in mind by the investigating of the South Korean Coast Guard 139. (31264)
