What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) This uncertified individual was attempting a takeoff in an uncertified, unregistered ultralight gyrocopter. When he applied excessive nose up pitch control the vehicle over rotated. The rotor struck the ground to the rear of the vehicle. The vehicle left the ground but immediately returned with sufficient force to cause substantial damage to its structure.
