Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The inexperienced student pilot applied excessive main rotorcontrol inputs while flying on the downwind leg of the traffic pattern. The main rotor blades flexed downward and severed the pushing propeller and empennage. The gyroplane pitched forward and collided with the ground.
