Mmmm ....
As per OldLae's quote above ... which brings me back to my post #3 at the beginning of this .... no doubt the persons bringing this charge may well prove that the flying characteristics of the a/c
MAY have been varied (and they may well test fly an a/c to prove same) .... this in itself I would predict would prove a lack of knowledge in preparing the a/c for flight and thus would constitute recklessness ....
Good luck
