The Operations Supervisor reported that the instructional flight with an unmanned aerial vehicle (UAV) was programmed for a single takeoff and traffic pattern to a full-stop landing. During the pre-landing checks, the pilot under instruction selected the incorrect landing profile, which did not account for the current runway displaced threshold because of runway construction. Shortly before touchdown, the pilot initiated a go-around but the landing gear impacted a runway trench, and subsequently the UAV impacted the ground. A post-crash fire ensued and the UAV was destroyed. The supervisor added that neither the instructor pilot nor the pilot receiving instruction spotted the incorrect selection during the pre-landing checks.
Probable Cause: The pilot's incorrect automated landing profile selection, which resulted in an impact with a runway trench. Contributing to the accident was the pilot receiving instruction's and instructor's failure to spot the incorrect landing profile selection during prelanding checks.
