It's a distortion if true. I have no clue. What's the factual
basis for your clue?

Hm, does the NTSB necessarily know about crash-related
insurance claims, settlements, or lawsuits?

If NTSB answers the telephone. If there's substantial hull damage
or serious injury, I think the ins co, and/or a plaintiff's att'y,
expects FAA/NTSB to know about it and for them to proceed if they
didn't know.

If a plaintiff says a flight was a YE flight and the EAA
denies it,

The truth will be sought in the usual way in which plaintiffs
discover evidence, such as sworn depositions.
