1) LOSS of control (LOC) accidents, involved an in flight: loss of main rotor control; structural failure of the main rotor blade that did not involve preexisting fatigue of rotor blade materials; or, loss of aircraft control or collision with terrain for unknown reasons, in the absence of structural failure,encounter with instrument meteorological conditions, or pilot impairment due to drugs or alcohol.
