From the cited (18 U.S.C. 32):
> Amendments to 18 U.S.C. § 32 enacted in 1984 expand United States jurisdiction over aircraft sabotage to include destruction of any aircraft in the special aircraft jurisdiction of the United States or any civil aircraft used, operated or employed in interstate, overseas, or foreign air commerce.
The special aircraft jurisdiction in question requires the aircraft to be “in flight”, where the definition of “in flight” oddly enough depends on the aircraft having “doors”.[1]
A plain reading of the statute indicates that it does not apply to unmanned aircraft unless they are engaged in interstate commerce. But I am not a lawyer.
> engaged in the authorized operation of such aircraft
Perpetrating a crime like criminal trespass or harassment is by definition not an authorized operation of any aircraft.
An FAA advisory on the topic [2] claims broad authority to supersede local regulation, but is careful to refer only to “navigable airspace”, and notes that
> Laws traditionally related to state and local police power – including land use, zoning, privacy, trespass, and law enforcement operations – generally are not subject to federal regulation.
I should have been more careful in my wording in the above comment. What you can and cannot do to a trespassing unmanned drone operating below the navigable airspace ceiling on your property is going to depend on the applicable state and local laws. For example, most municipalities have laws against use of firearms within city limits.
