GW_04....agree with you on all but one point. The 310R is a bit touchy in the
forward C of G range. It's a lot harder to load behind the aft limit.
There was a flight training organisation not far from here who departed on their IFR navs with the a/c loaded beyond the forward C of G just by having full mains with only the instructor and student on board.
A heavy nav bag stored behind the rear seats may have got them back within limits.
