On July 4, 1986, a Piper PA-31 Cheyenne (registration GN-750) operated by National Argentinian Police was involved in an aviation accident near Gualeguaychu, Argentina in flight. 6 people were killed. Investigators recorded the probable cause as: The aircraft struck power cables while flying at a low altitude, causing a stall and subsequent crash. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A); 3 related events involving the same aircraft type or operator are linked below.
A twin-engine aircraft crashed into a field and caught fire after striking electrical cables during low-altitude flight, resulting in no survivors.
What happened
During a period of low-altitude cruise, a twin-engine aircraft collided with overhead power cables. The impact caused the aircraft to enter a stall condition, leading to a subsequent crash into a pasture. Upon impact with the ground, the wreckage ignited, resulting in a large fire.
There were six fatalities recorded as a result of the accident, with no survivors reported among the occupants of the plane.
Findings
The aircraft struck electrical infrastructure during its flight phase.
The collision led to an immediate loss of lift and an aerodynamic stall.
The subsequent impact with the terrain caused the airframe to burst into flames.
Probable cause
The aircraft struck power cables while flying at a low altitude, causing a stall and subsequent crash.
