It's certainly more than an 'incident'.
Definition of 'accident'-
An unexpected and undesirable event, especially one resulting in damage or harm
A nosleg collapse or hangup will undoubtedly have damaged the surface of the runway, never mind the aircraft.
We'd certainly categorise this occurrence as an 'Accident' and reportable as such.
Perhaps 'crash' is going a bit too far, dictionary definition of 'crash' is
To undergo sudden damage or destruction on impact
