The Aircraft Accidents Investigations Bureau of Ghana (AAIBG) has revealed that a sudden and powerful downdraft and bad weather were responsible for the crash.
The accident claimed the lives of all three crew and five passengers on board.
The report outlined several findings and recommendations.
Cause of crash: The helicopter lost lift and altitude due to a downdraft caused by poor weather and rugged terrain.
Aircraft condition: The Z-9EH helicopter was airworthy but lacked terrain awareness, autopilot, and advanced navigation systems.
Crew competence: The pilots were fully qualified, well-rested, and medically fit, with no evidence of fatigue or human error.
Weather conditions: Visibility dropped to about 200 metres near Obuasi, with mist, rain, and low clouds forcing instrument flying.
Emergency response: Rescue teams reached the crash site within two hours despite difficult terrain and bad weather.
Systemic issues: The Air Force lacked real-time tracking systems, flight data monitoring, and simulator-based training.
