Description
During airwork, the remotely piloted aircraft (RPA) lost power to a motor resulting in the RPA entering an uncontrolled descent and subsequently colliding with the roof of a house. The RPA was substantially damaged.
Reported Cause
The engineering inspection revealed the inertial measurement unit had failed and the flight controller had caused the RPA to switch to attitude mode which has shut down the propulsion systems uncommanded.
