A UAS pilot reported a loss of aircraft control and subsequent UAS crash. The manufacturer examined the parts and found faulty receiver components.

Narrative

Title: Loss of Drone Control Due to Remote Controller Main Board Failure -- DJI Mini 3 ProEvent Summary:During a routine flight with a DJI Mini 3 Pro; I experienced a sudden and total loss of control of the drone while it was overhead at normal operating altitude. The drone became completely unresponsive to input and ultimately crashed. Conditions were clear; there was no interference; and the drone was within line of sight.After the incident; DJI analyzed the remote controller and confirmed a main board malfunction; which caused 'abnormal sensitivity of operation.' The remote controller was essentially new; with less than one hour of total flight time; no history of abuse; drops; or moisture damage. Despite confirming the hardware defect; DJI refused to cover the repair under warranty; citing that the warranty period had expired; and assessed $XXX.XX for replacement/repair.Safety Concern for Other Operators:A sudden loss of control due to internal remote hardware failure poses a serious risk to property; bystanders; and airspace safety. Operators should be aware that even lightly used or seemingly reliable remotes can fail catastrophically without warning. Additionally; this highlights a potential gap in manufacturer accountability when failures occur outside warranty periods; even if clearly related to defective components.NOTE: I have no idea if the situation I faced is occurring to any other owner of a mini 3 pro drone. I am disappointed in DJI's response to what I think is a serious issue. I have no problem with paying to replace a controller with a documented hardware issue. DJI; to date; refuses to address the hardware issue; i.e. manufacturing defect? Fortunately; no one was hurt. No property beyond the drone damaged. A drone that fails to respond to commands inc RTH is a drone operator's greatest concern.
