A Tecnam P92 Echo Classic, took off from Puan's aerodrome (Buenos Aires) at 14:45 hours, in order to make a local flight, with a pilot and a passenger.
After 40 minutes of flight in visual flight conditions at 2000 feet, and heading east, the pilot decided to descend in order to find conditions with less turbulence. At an altitude approximately 1500 feet, the pilot reduced power to idle and then the engine stopped.
After several unsuccessful attempts to restart the engine, the pilot decided to perform a emergency landing on provincial route 76. During the descent, the aircraft impacted against a power line that crossed the route, continued to fly and landed without other inconvenience in a lateral field.
As a consequence of the event, the aircraft experienced damage to the fuselage, the landing, the left wing and the propeller.

Conclusions regarding factors related to the accident
- The LV-S026 was operated with super naphtha, with a 12% ethanol content as indicated in its technical data sheet.
- Provision 224/10 of ANAC prohibits the use of automotive fuels marketed in the Republic of Argentina.
- Rotax does not allow the use of automotive fuels whose ethanol content exceeds 10%.
- According to the Tecnam P92 Echo Classic flight manual, automotive fuel can be used without any limitation regarding ethanol content.
- The loss of engine power probably occurred due to fuel vaporization in the engine feed line.
