What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
A student sport pilot made a hard landing on MARCH30, 2011AT approximately 1630 hrs at the Pinconning, Michigan airport (gross 52I).the student pilot stated that he made a small adjustment to the horizontal stabilizer and wanted to see how much of a difference the adjustment had made. The auto gyro plane unexpectedly got off the ground and he had to go around the traffic pattern to land. He had noticed his decent was too steep and could not correct in time and landed hard on the 2600 foot long and 100 feet wide turf runway. He said that after he hit the runway hard the experimental built auto gyro bounced 20 to 25 feet in the air. The plane had tricycle gear made of fiberglass and was very springy. When the aircraft came down the second time the two bladed main rotors contacted the aft engine propeller damaging the propeller main rotor and vertical stab. The pilot was taken to a near by hospital for a possible concussion as a precaution. When I had contacted him by phone the following day he stated that he didn't intend to fly but the autogyroplane got airborne because of the horizontal stabilizer adjustment. His 90 day solo endorsement had expired and was not current to fly solo.
