92 Ill. Adm. Code 14.1010
Liability
Section 14.1010 Liability
The pilot-in-command and/or owner of an ultralight aircraft,
operating to or from an uncertificated area shall be responsible for, and by so
operating shall assume, the responsibility for any liability that may arise out
of these operations. This Part shall not be interpreted as, nor does it give
the pilot-in-command of the aircraft the right to trespass upon the property of
another. The foregoing does not relieve a property owner from liability to
invitees for damage arising from defects for which they have actual or
constructive knowledge.
