What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
An ultralight aircraft departed the non-towered airfield and was attempting to land back at the airfield when the pilot loss control of the aircraft. The pilot appeared to have trouble controlling the aircraft in flight while on approach to the landing runway. The pilot flew into the active airport runway air space, which was not standard operating procedure for ultralights at this airport. The ultralights have their own landing area away from the active runway. The aircraft was about 300 feet above and 100 feet behind the active runway 16 and appeared to be climbing when the aircraft suddenly rolled over, loss altitude, and broke up in-flight. The pilot did not survive, and the wreckage landed to the right of the active runway 16. The aircraft did not meet the requirements to be an ultralight under CFR 103. This aircraft was modified beyond the requirements of CFR 103 and was an illegally operated uncertificated aircraft. Furthermore, it had non-airworthy maintenance repairs to the front wing spar. Which could have contributed to the pilot's loss of control and the in-flight breakup of the aircraft.

THE AIRCRAFT WAS ABOUT 300 FEET ABOVE AND 100 FEET BEHIND THE ACTIVE RUNWAY 16 AND APPEARED TO BE CLIMBING WHEN THE AIRCRAFT SUDDENLY ROLLED OVER, LOSS ALTITUDE, AND BROKE UP IN-FLIGHT. THE PILOT DID NOT SURVIVE, AND THE WRECKAGE LANDED TO THE RIGHT OF THE ACTIVE RUNWAY 16. THE AIRCRAFT DID NOT MEET THE REQUIREMENTS TO BE AN ULTRALIGHT UNDER CFR 103. THIS AIRCRAFT WAS MODIFIED BEYOND THE REQUIREMENTS OF CFR 103 AND WAS AN ILLEGALLY OPERATED UNCERTIFICATED AIRCRAFT. FURTHERMORE, IT HAD NON-AIRWORTHY MAINTENANCE REPAIRS TO THE FRONT WING SPAR.
