Introduction
On June 8, 2019, at 21:00 UTC, a Sport EIT2 aircraft, registration LV-X511, departed from runway 33 of Belén de Escobar Aerodrome in Buenos Aires, Argentina, for a general aviation test flight. The aircraft was destroyed upon impact, and the pilot, who was also the owner, died. The accident occurred during daylight in good meteorological conditions.
Flight History
During the initial climb, the pilot executed a left turn at low speed, lost control of the aircraft, and subsequently impacted the ground. The pilot had installed a variable pitch propeller system on the aircraft and was performing the first test flight with that modification.
Aircraft Information
The Sport EIT2 (registration LV-X511) was an experimental aircraft. It had undergone a major alteration—specifically, a design change to the propeller hub and pitch control system—that was not reported to the Administración Nacional de Aviación Civil (ANAC). The aircraft was not certified in accordance with current regulations. The airframe was destroyed, the engine sustained significant damage, and the propeller was destroyed.
Pilot Information
The pilot, a 56-year-old Argentine male, held a commercial pilot license (first class) and instructor ratings for airplane and glider. He had endorsements for single-engine land, multi-engine land, glider towing, instrument flight, and night flight. His medical certification (Class 2) was valid until July 31, 2021. The investigation could not access the pilot's logbook.
Conclusion
The report details the circumstances surrounding the accident and raises safety issues related to modifications made to experimental aircraft. A safety recommendation was issued to the Asociación Argentina de Aviación Experimental.
