Had he cooperated, it's plausible to see him getting away with a license revocation and fine. Instead he did this:
"In the weeks following the plane crash, Jacob lied to investigators that he did not know the wreckage’s location. In fact, on December 10, 2021, Jacob and a friend flew by helicopter to the wreckage site. There, Jacob used straps to secure the wreckage, which the helicopter lifted and carried to Rancho Sisquoc in Santa Barbara County, where it was loaded onto a trailer attached to Jacob’s pickup truck.
Jacob drove the wreckage to Lompoc City Airport and unloaded it in a hangar. He then cut up and destroyed the airplane wreckage and, over the course of a few days, deposited the detached parts of the wrecked airplane into trash bins at the airport and elsewhere, which was done with the intent to obstruct federal authorities from investigating the November 24 plane crash."
