Here is the link to NTSB Part 830....

The key part seems to be shown in "830.2 Definitions". To me this
doesn't really apply to an uneventful landout...except that (like most
FAA/NTSB documentation) it is open to interpretation.

"Aircraft accident means an occurrence associated with the operation
of an aircraft which takes place between the time any person boards
the aircraft with the intention of flight and all such persons have
disembarked, and in which any person suffers death or serious injury,
or in which the aircraft receives substantial damage."

"Incident means an occurrence other than an accident, associated with
the operation of an aircraft, which affects or could affect the safety
of operations."
