The official investigation into the August 6, 2025, Ghana Air Force helicopter crash has concluded that the accident was caused by a sudden downdraft and poor weather conditions over hilly terrain in the Ashanti Region.
The tragedy claimed eight lives, including two cabinet ministers, and has been described as one of the darkest days in Ghana’s aviation history.
The findings were announced at a media briefing in Accra on Tuesday, November 11, 2025, a day after the final report was submitted to the National Security Council.
Cause of the Crash
Captain Paul Fordjour, Aircraft Accident Investigator and Head of Investigations at the Aircraft Investigation Bureau (AIB) Ghana, said the Harbin Z-9EH helicopter operated by the Ghana Air Force was mechanically sound and airworthy but lacked modern safety systems that could have helped the pilots avoid the fatal descent.
“The helicopter was in good working condition and met all basic safety requirements,” Captain Fordjour explained. “However, it did not have advanced systems such as terrain awareness and warning equipment, automatic flight control, or navigation mapping, which could have enhanced situational awareness and reduced pilot workload.”
According to the report, the aircraft lost altitude after encountering a powerful downdraft caused by deteriorating weather conditions while flying over the Dampia Range Forest Reserve near Antoakrom in the Amansie West District.
Sequence of Events
The Z-9EH helicopter, with tail number GHF 631, had departed Accra at about 9:12 a.m. for Obuasi on an anti-illegal mining mission. The crew had delayed takeoff for an hour due to poor weather but proceeded under visual flight rules.
As the aircraft approached Obuasi, visibility dropped sharply to about 200 metres amid mist, rain, and low clouds, forcing the pilots to switch to instrument flight rules. Moments before impact, the crew reported sighting high ground ahead, before the helicopter lost lift and struck a ridgeline at roughly 1,370 feet above sea level.
Captain Fordjour said data from the flight recorders—decoded at the Aviation Industry Corporation of China (AVIC) centre in Xi’an—confirmed that the loss of altitude occurred without any change in engine power or pitch attitude, consistent with a downdraft caused by changing weather over high terrain.
Findings from the Investigation
The 30-day investigation, chaired by National Security Coordinator Abdul-Osman Razak and supported by technical advisers from the United States Air Force, found no evidence of mechanical failure, human error, or medical impairment.
The pilots, the report noted, were experienced, well-rested, medically fit, and fully qualified under both Ghana Air Force and international aviation standards.
Among those who perished were Edward Omane Boamah, Minister for Defence, Ibrahim Murtala Muhammed, Minister for Environment, Science, Technology and Innovation, Limuna Muniru, Acting Deputy National Security Coordinator, Samuel Sarpong, NDC National Vice Chairman, Samuel Aboagye, Deputy Director-General, NADMO and And three Air Force crew members.
Emergency Response and Systemic Issues
Despite difficult terrain, heavy rain, and poor visibility, emergency teams reached the crash site within two hours. Captain Fordjour praised their swift response, calling it “timely and commendable under very challenging circumstances.”
However, the inquiry also highlighted broader weaknesses in Ghana’s aviation system, including
Inadequate real-time weather services, limited simulator training for pilots and absence of flight-tracking and data-monitoring systems.
Recommendations
The AIB Ghana made several recommendations to enhance aviation safety:
- Acquire aircraft equipped with terrain awareness, autopilot, and advanced navigation systems
- Invest in flight simulators for pilot training
- Establish national en-route navigational aids and real-time weather monitoring systems
- Install modern cockpit voice and flight data recorders with audiovisual capabilities
- Modernize ground support and flight data systems
Captain Fordjour described the crash as a tragic, weather-related accident that exposed critical gaps in the nation’s aviation infrastructure.
“We hope this report brings closure to the families of our departed heroes and to the nation,” he said. “The lessons learned must guide reforms to make our skies safer.
