What happened
On June 28, 2025, at the EEVS airfield, a pilot conducted three separate flight operations using an S-18T.2, registration RA-0856G. Two of these flights were performed within Class G airspace. The aircraft carried the pilot and various passengers. The pilot proceeded with these flights without notifying the aircraft owner of the intent to fly, and failed to provide the necessary notifications to Air Traffic Control (ATC) services regarding the planned operations.
Prior to the flights, the aircraft underwent engine startup, testing, and taxiing from the parking area to a temporary parking spot. These ground operations were performed by individuals who did not hold valid aviation personnel certificates. Additionally, the pilot did not request meteorological information from the official weather service, likely making decisions based on observed local weather conditions, which were suitable for Visual Flight Rules (VFR).
The investigation
The investigation was conducted using witness statements, the owner's explanations, and an inspection of the accident site and aircraft components. Because the aircraft lacked standard flight parameter recording equipment, the flight history could not be retrieved from onboard data.
Due to a ground fire at the airfield, the investigation team was unable to verify the completeness of the pre-flight preparations or the exact amount of fuel loaded onto the aircraft. The owner stated that all relevant operational and maintenance documentation was located on the aircraft at the time of the incident and was subsequently unavailable due to the fire.
Findings
- The pilot failed to notify ATC services of the flights in Class G airspace, violating established airspace usage regulations.
- The pilot did not notify the aircraft owner of the flight intentions.
- Ground operations, including engine testing and taxiing, were conducted by unauthorized personnel lacking proper certification.
- The pilot did not undergo a pre-flight medical examination.
- The pilot did not obtain official meteorological briefings prior to departure.
