What happened
Two Grumman Ag Cat aircraft, both operated by the same air service, were involved in a mid-air collision. The incident occurred while one aircraft was departing from a temporary airstrip adjacent to fields being fertilized, and the other was returning to that same location.
Eyewitnesses indicated that both pilots attempted to avoid the other aircraft by pulling up. The older pilot, who was also the owner of the air service, was found to have low cholinesterase levels in his toxicological sample.
The investigation
Investigators examined the circumstances surrounding the collision and the health status of the pilots involved. The presence of low cholinesterase in the older pilot's system was noted as a potential factor.
Findings
The collision resulted in fatal outcomes for those involved. The investigation highlighted the risks associated with agricultural aviation operations, particularly when multiple aircraft are operating in close proximity. The low cholinesterase level in the older pilot's toxicological sample suggests possible exposure to organophosphate or carbamate pesticides, which can impair cognitive and motor functions.
Safety message
Pilots engaged in agricultural operations should be aware of the potential effects of pesticide exposure on their health and performance. Regular medical check-ups and adherence to safety protocols are essential to mitigate risks associated with such operations.
