Narrative:In 43rd test flight at 700 m altitude main rotor blades failed, test pilot Semyon Kozyryev bailed out, but was hit with a blade and died.
Years after the crash it has been attributed to the unsatisfactory design of the rotor blades, in which the phenomena of fatigue of the spar material under variable dynamic loads were not taken into account.
