A pilot taking medication for diabetes blacked out immediately after departing a westbound airstrip, causing the aircraft to enter a right spiral before crashing into the ground.

What happened

The pilot departed from an airstrip located to the west with plans for a very brief flight lasting only three to five minutes. Shortly after leaving the ground, the pilot lost consciousness without warning. The aircraft immediately entered a steep right-hand spiral and continued descending until it impacted the terrain.

The investigation

Investigation into the circumstances surrounding the crash revealed that the pilot was managing a mild diabetic condition by taking Glucotrol, a medication designed to lower blood glucose levels. At the time of the incident, the pilot had just finished eating a large breakfast.

Findings

The sequence of events suggests a medical episode rather than a mechanical failure or weather-related issue. The combination of recent food intake and medication for diabetes likely contributed to the sudden loss of consciousness. The pilot was not able to maintain control of the aircraft due to this incapacitation, leading directly to the crash.

Safety message

Pilots managing medical conditions such as diabetes must be aware of how medications like Glucotrol can interact with food intake and daily activities. Sudden incapacitation poses a severe risk during critical phases of flight, particularly immediately after takeoff when altitude is low.

Probable cause

The pilot's temporary loss of consciousness due to the effects of diabetes medication taken for a mild diabetic condition.
