What happened
The commercial pilot was operating an aircraft on a routine aerial observation flight. During the operation, the aircraft was maintaining an altitude of approximately 500 feet above ground level when it suddenly began an uncontrollable descent. The pilot attributed this loss of control to encountering windshear conditions at that low altitude.
The investigation
Following the incident, a thorough inspection of the aircraft was conducted to determine the cause of the event. The examination revealed no evidence of pre-accident mechanical malfunctions or failures that would have contributed to the accident.
Findings
Meteorological data and conditions at the time of the flight were analyzed. The investigation determined that the weather conditions present were conducive to the formation of low-level windshear, which likely caused the aircraft's descent.
low-level windshear was identified as the primary environmental factor contributing to the loss of control during the observation mission.
