Because it makes sense. The changes imposed by mod 73 enhance the safety
of the aircraft. The pip pins are intended to hinder outboard movements
of the tail plane, not to take over torque loads. So changing the design
so that the parts involved can only do what they are supposed to do, and
nothing else, is a valuable improvement.
Whether a real accident has happened or not is not really my concern.
The good thing about the accident was that is was a reason to look again
with an eagle eye to the design of the Europa, and to correct any
(theoretical) flaws. Mod 73 was a result of that.
