From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

On August 27, 2019 at approximately 1600 hours a small UAS had a failure during flight and crashed striking two parked vehicles in the process causing property damage that exceeds $500.

The suas was being operated by remote pilot in command privacy data omitted who was contracted by menet aero to perform a tethered traffic analysis flight. The event occurred approximately 1 hour into the planned 3 hour flight.

Examination of the suas post accident showed structural failure similar to failures found on other suas of the same make and model via internet search. Several rotor blades were broken due to impact as well one of the booms that supports the motors. One motor was completely separated from the broken boom. The metal bracket that joins to boom to the main structure was craked in several places as well. Either a rotor or airframe structural failure occurred during flight possibly due to a momentary high wind gust. The failure caused the aircraft to go into its lost motor failsafe mode where it spins and descends until impact.
