What happened
On February 26, 2026, a Piper PA-36 375, registration LV-OGL, was engaged in agricultural maneuvering in Argentina when the aircraft experienced a significant reduction in engine performance. During the flight, the pilot reported that the powerplant was producing approximately 80% of its rated power. Following this loss of power, the aircraft impacted a cultivated field located less than 10 km from the aerodrome. The impact occurred at a low speed with the aircraft in a level pitch and wing attitude. While the aircraft sustained substantial damage, the pilot escaped the wreckage within one minute and sustained no injuries.
The investigation
Preliminary investigations by the JST focused on the mechanical performance of the Lycoming 720 family engine and the propeller system. The investigation established that the aircraft was operating under Visual Meteorological Conditions (VMC) with 12 km visibility and calm winds. The aircraft, a 1984 model, was being operated by a private owner for agricultural purposes. Investigators examined the engine's power output and the circumstances surrounding the sudden drop to 80% power during the maneuvering phase of flight.
Findings
- The primary factor contributing to the accident was a powerplant failure or malfunction resulting in a loss of approximately 20% of available engine power.
- The aircraft was in a maneuvering phase of flight when the power loss occurred.
- The impact took place in a field of crops/cultivated land at a low velocity.
- The pilot was able to exit the aircraft quickly following the impact.
