Synopsis
Recreational / Hobbyist UAS pilot reported they were using manual flight mode during cruise flight when UAS made a noncommanded right hand turn into a nearby tree. The UAS suffered minor damage and was recovered.
Narrative
I got authorization to fly recreationally. I was in a nice cruise down a trail while maintaining visual [line] of sight when the drone made a hard right turn into a tree. The drone had acted up near that spot by coming to a slow stop and about 600 feet later did the same thing. All sensors were turned off and the flight was in sports mode. No one or property was injured in the accident except for my props. The drone flight data shows the drone made a hard right turn into the trees while the stick was pointed to the left. I believe that local interference caused my drone to turn and crash into the trees. There is at least one tower with a microwave transmitter near by; along with the Water Treatment Facility. I contacted the FCC who said file a police report. I am worried that someone was using a jamming device or that the transmissions might be too powerful and interfered with my GPS signal/control of the drone during the flight which might also interfere with manned aircraft. I had no errors on my controller that I can see from the data.
NASA callback
Reporter indicated they believed microwave radio interference from a nearby tower was the root cause of the loss of UAS control. The UAS flew fine after the incident in other areas. The reporter indicated they were flying with LAANC approval. They did not have any waivers; exemptions; or other authorizations.
