A pilot flying an agricultural aircraft crashed into a tree while spreading fertilizer, suffering a head injury and pneumonia.

What happened

The accident occurred while the pilot was conducting an agricultural operation. The aircraft was approaching a field with the specific intent of spreading fertilizer. During the approach phase, the airplane collided with a tree and subsequently crashed to the ground.

Following the impact, the pilot sustained a head injury. When questioned about the events leading up to the crash, the pilot reported that he could not recall the accident itself. Medical records obtained from the hospital treated the pilot revealed significant health issues at the time of the incident. The pilot was suffering from pneumonia and had a body temperature of 101 degrees Fahrenheit when the accident took place.

The investigation

An examination of the aircraft engine was conducted to determine its operational status prior to the impact. A witness who observed the flight stated that the engine was running normally immediately before the accident occurred. This testimony suggests that a mechanical failure or engine malfunction was not the primary factor in the loss of control.

Findings

The investigation highlighted the pilot's physical condition as a critical element in the sequence of events. The presence of pneumonia and a high fever likely contributed to the pilot's inability to recall the accident and may have impaired his ability to safely operate the aircraft during the approach. The witness statement confirming normal engine operation further isolates the cause to the pilot's health rather than equipment failure.

Probable cause

The pilot's impairment due to pneumonia, which resulted in a loss of control during the approach phase.
