Analysis 

The pilot reported that this was his first flight in the accident gyroplane. He added that, during takeoff from runway 15, which was 6,001 ft long by 100 ft wide, he centered the gyroplane on the runway and increased engine rpm and rotor speed. Around 120 rotor rpm during the takeoff roll, he pulled back on the cyclic. Due to his injuries sustained in the accident, he does not recall what occurred afterward.

The gyroplane came to rest on its right side on the right side of the runway and sustained substantial damage to the empennage.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the gyroplane that would have precluded normal operation.

The automated weather observation station located on the airport reported that, about 5 minutes before the accident, the wind was from 260° at 7 knots. The same automated station reported that, about 15 minutes after the accident, the wind was from 330° at 5 knots. The gyrocopter was departing runway 15.
