  The growth kinetics is studied of free-growing helium crystals within the
temperature range 0.5-0.83 K and supersaturations to 10 mbar. For the pressure
supersaturations above 0.5 mbar, numerous drastic changes are observed in the
growth kinetics for all crystalline facets from the normal and slow kinetics to
the anomalously high or burst-like one. It is found for the first time that the
anomalous to normal transition in the facet growth kinetics occurs in a jump
like manner within a time 80 {\mu}s interval of the measurement record.
