Description
During the landing sequence at 30 ft, the remotely piloted aircraft (RPA) became unresponsive to control inputs and made an uncommanded roll to the right. The RPA collided with terrain resulting in substantial damage.
Reported Cause
The flight data revealed the reverse thrust activated earlier than it should have resulting in reduced airspeed and subsequent stall.
