This is just wrong.
Public Law 112–95 Sec. 336. Special Rule For Model Aircraft says:
(b) STATUTORY CONSTRUCTION.—Nothing in this section shall
be construed to limit the authority of the Administrator to pursue
enforcement action against persons operating model aircraft who endanger
the safety of the national airspace system.
This does not make all FAR's enforceable on model aircraft. In fact the only FAR that could apply is 91.13 Careless and Reckless. That's all they need. You can't name a single other rule that would apply to model aircraft.
91.13 is so ridiculously broad that the FAA could bust the kid with a balsa wood hand-launched glider. They really don't need any other rules
Are you referring to the Pirker decision?
The first decision:
When respondent moved to dismiss the complaint, he argued the Federal Aviation
Regulations (FARs),3 which govern the operation of “aircraft,” did not apply to respondent’s
Ritewing Zephyr. In this regard, respondent argued the aircraft was a “model aircraft” not
subject to the regulatory provisions applicable to “aircraft.” After considering the parties’
written submissions on the motion, the law judge concluded in his decisional order the Zephyr
was a “model aircraft” to which § 91.13(a) did not apply.
And the second decision:
C. Conclusion
This case calls upon us to ascertain a clear, reasonable definition of “aircraft” for
purposes of the prohibition on careless and reckless operation in 14 C.F.R. § 91.13(a). We must
look no further than the clear, unambiguous plain language of 49 U.S.C. § 40102(a)(6) and 14
C.F.R. § 1.1: an “aircraft” is any “device” “used for flight in the air.” This definition includes
any aircraft, manned or unmanned, large or small. The prohibition on careless and reckless
operation in § 91.13(a) applies with respect to the operation of any “aircraft” other than those
subject to parts 101 and 103. We therefore remand to the law judge for a full factual hearing to
determine whether respondent operated the aircraft “in a careless or reckless manner so as to
endanger the life or property of another,” contrary to § 91.13(a).
The Pirker decision said only that 91.13 applies to all aircraft including model aircraft.
There is nothing in the FARs or Pirker decision that says model aircraft must follow "the same FARs as manned aircraft".
