What happened
On May 16, 2020, an experimental RV-10, registration PP-ZGA, departed from an unregistered airfield in Japurá, Amazonas, bound for Porto Vel for a private ferry flight. The flight, carrying a pilot and three passengers, diverted to the Lábrea Aerodrome (SWLB) during the mission.
Upon attempting to land on runway 36, the aircraft touched down approximately halfway down the runway. The aircraft failed to stop within the remaining pavement, overran the threshold, and traveled 190 meters into soft terrain and low vegetation. While the pilot reported a perceived brake failure, passenger testimony suggested the aircraft was approaching with excessive speed. The impact resulted in substantial damage to the aircraft, though all four occupants escaped without injury.
The investigation
CENIPA's investigation revealed several critical regulatory and operational discrepancies. The aircraft was being ferried under a legal authorization to move it to Porto Velho for maintenance, yet it lacked a valid Experimental Flight Authorization (CAVE), rendering it unairworthy for the flight. Furthermore, the aircraft's maintenance records contained errors, including an incorrect registration number.
The investigation also noted that the flight originated from an unregistered airfield, which violates Brazilian aeronautical regulations. While the pilot was qualified to fly the aircraft type, he had limited experience with the RV-10 model, with only approximately 20 flight hours in the type. Additionally, the landing on runway 36 was prohibited by the ROTAER due to bird activity near the threshold.
Findings
- The pilot's unstable approach and landing parameters were primary factors in the runway excursion.
- The pilot's limited experience with the specific aircraft model contributed to the incident.
- The aircraft was operating without the required Experimental Flight Authorization (CAVE).
- The flight departed from an unregistered airfield.
- The landing occurred on a runway segment that was restricted due to bird concentration.
