What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Small unmanned aircraft (ua) registration number: FA3LRENEWE.
Make/model: dji matrice 200 V2, s/n 17S3H7U002U016.
Operating frequency: 2.400-2.483 ghz and 5.725-5.850 ghz.
Remote pilot certificate #: 4455913.
The ua departed controlled cruise flight and impacted a private residence damaging its metal roof. The estimated cost to repair the property damage exceeded the accident reporting threshold specified in 14 CFR part 107. The pilot operating the ua at the time of the accident was doing so on behalf of the city of Rushville Indiana for the purpose of area mapping and flight training/practice. The accident flight originated at the Rushville riverside park at approximately 11:18 EST. Following the mapping portion of the flight the pilot commanded the ua southward to a cruise altitude of 400 feet. At the 5:53 minute flight duration mark the ua flight controller sounded a "no connection” alarm and the pilot lost visual contact with the ua. The pilot waited for the ua to execute its lost link point protocols and either restore the lost connection or autoland. Neither of those events occurred. The ua flight controller recorded the telemetry data sent from the ua up until the “no connection” alarm occurred. The last reported telemetry data indicated the ua was travelling 51 mph at 399 feet AGL and was 3,238 feet from the ua controller location. The ua was sent to the manufacturer (dji) for evaluation and dji reported that the ua had experienced an unspecified hardware failure which caused it to depart from controlled flight.
