What happened
On March 23, 2021, a Starflight Fox V-5 Super ultralight aircraft, registered as PU-MHB, was performing a local recreational flight near Piracanjuba, Goiás. The flight, intended to be a scenic tour over the city, was carrying a pilot and one passenger. During the flight, the aircraft experienced an engine failure. While attempting an emergency landing in an open field, the aircraft struck high-voltage power lines seconds before impacting the ground. Despite the substantial damage sustained by the aircraft, both occupants emerged uninjured.
The investigation
CENIPA investigators established that the individual operating the aircraft did not possess a valid pilot license, certificate, or any aeronautical qualification registered with the National Civil Aviation Agency (ANAC). Furthermore, the operator lacked a valid Aeronautical Medical Certificate (CMA) and had no verifiable training or experience in operating this type of aircraft. The investigation also noted that the operator was not registered with any national ultralight associations capable of issuing medical declarations.
Regarding the aircraft's airworthiness, investigators were unable to verify the validity of the Experimental Flight Authorization Certificate (CAVE) because the mandatory Annual Maintenance Inspection Report (RIAM) was not available for review. Additionally, the lack of access to technical logs for the engine, airframe, and propeller meant that investigators could not confirm if maintenance was being performed according to the manufacturer's requirements or if the aircraft was within weight and balance limits. While weather conditions were favorable for visual flight, the operation was conducted in total disregard of established Brazilian civil aviation regulations.
Findings
- The engine failed during flight.
- The aircraft collided with high-voltage electrical wires during the emergency maneuver.
- The operator lacked all required aeronautical licenses, certificates, and medical certification.
- The operator lacked the necessary training and skills to manage the engine failure according to manufacturer procedures.
- The operation was conducted in violation of aeronautical regulations, resulting in safety levels significantly below the minimum standards required by the Brazilian State.
