Flight History
On May 8, 2026, starting at 18:35, a pilot was conducting agricultural spraying operations using a DJI Agras T50 unmanned aerial vehicle (UAV) at a horticultural center in Goczałkowice Zdrój. The spray route was divided into stages due to the large area; between stages, the pilot replaced the battery and refilled the spray agent. The programmed flight altitude during spraying was 3.5 m above ground, with a transit altitude of 6 m. The route, stage division, and sequence were generated by flight planning software.
Prior to the accident, the pilot observed two anomalies: the UAV did not respond to a Return-to-Home command and did not land on command, and it once hovered unresponsive for several minutes before automatically landing when the battery reached a critical level. Both anomalies were resolved after a battery replacement and system reset.
During the start of a stage, the UAV ascended to transit altitude, turned approximately 160° from the spray direction, and during transit struck a medium-voltage power line crossing the sprayed area. The impact severed the wires, causing a short circuit and a small fire.
Aircraft and Pilot Information
The UAV was a DJI Agras T50, registration 7TNBMFP0030BUU. The pilot held a certificate of competence for open category A1/A3 and A2, as well as specific category STS-01, and had completed competency training on the DJI Agras T30 and T50 types two months before the event.
Damages
The UAV was destroyed, with damage including a cracked fuselage, damaged front camera mount, separation of the rear left motor, mechanical and thermal damage to the rear right drive unit, a broken front left arm, a cracked front left motor housing, damaged or broken rotor blades, and torn-off landing skids. The resulting fire also damaged a fence and several trees.
Investigation Actions
The Polish State Commission on Aircraft Accident Investigation (PKBWL) collected witness statements, copied logs from the UAV controller, verified the pilot's licenses, reconstructed the flight path, gathered weather data (including a meteogram from a station about 5 km away), and inspected the wreckage and accident site. No safety recommendations have been issued as of the preliminary report's publication.
