Why should he go to prison? Faking an airplane crash for YouTube views, while clearly in bad taste, doesn't seem worthy of jail time.

Reckless self endangerment maybe? But that also doesn't seem to rise to the level of "put you in jail".

If the crash was intentional, then he's certainly liable for violating littering laws by depositing a moderate amount of wreckage in the mountains which he didn't clean up. Again, not worthy of prison time. Probably a hefty fine though.

Last I can think of is if he makes a fraudulent insurance claim; in that case then yeah he might be eligible for jail time, but I don't think we know whether he filed an insurance claim in the first place.
