Sabotaging an aircraft is certainly a crime. Interfering in such a way as to prevent movement of an aircraft may possibly be legal. For example, non-payment of fees could warrant an aircraft being chained and padlocked in the same way a car can be wheel-clamped. I imagine that these days you would have to get the bailiff involved to do that. But blocking an aircraft with another, or with a vehicle etc, seems perfectly reasonable if someone has been a ********. Dickheads must be punished at every opportunity.....
I know of one case where a propeller was removed from an aircraft by a licensed engineer and not returned to the owner until the staff were paid money owing. Whether or not that was 'interfering' with an aircraft is a moot point, but the alternative of baseball bats in the staff carpark was loudly debated at the time. Legal action was the last thing on the employer's mind - he needed the revenue from the aeroplane to pay off other creditors, so somehow dredged up the missing wages. The engineer of course documented the removal and eventual replacement of the prop. Gotta love it.
