That seems a little untidy, but fortuitous for the insurer in this case. I would be denying the payout if that is true.
On the rotation comments, another aircraft with a curious rotate is the IAI Westwind I/II; the initial rotate requires nearly full back stick to get any movement of the nose in rotation, and then the aircraft starts to behave normally as the nose rises. Using small inputs will end up in a high-speed taxi towards the end fence. The trim setting is correct for the initial climb, it is just getting that nose to come off the ground that is curious. Lesser falcons than the 900 rotate beautifully, like most planes.
The insurer was not amused indeed => Case 3:21-cv-00758-GPC-BLM Document 33 Filed 02/24/22 as you can see the case is still running.
