The Nigerian Safety investigation Bureau (NSIB) has released an investigative report shedding light on the crash of a Sikorsky S76C helicopter, which occurred in October 2024 near the Atlantic Ocean. The incident claimed the lives of all eight individuals on board, including six passengers and two crew members. Operated by Eastwind Aviation Logistics Services Limited, the helicopter was on a routine drop-off and pick-up mission for oil workers when tragedy struck.
Key Findings from the NSIB Report
- Lack of Flight Data Recorder (FDR)
The report revealed that the helicopter was not equipped with a Flight Data Recorder (FDR), commonly referred to as a “black box.” The absence of this critical device has complicated efforts to determine the exact cause of the crash.According to Part 7.8.2.2(q) of the Nigerian Civil Aviation Regulations (Nig.CARs) 2023, all helicopters with a maximum takeoff weight between 3,175 kg and 7,000 kg must be fitted with an FDR. Despite this requirement, the Sikorsky S76C lacked this essential equipment.Explaining the importance of an FDR, the Director of Aerodrome and Airspace at the Nigeria Civil Aviation Authority (NCAA), Godwin Balang, said:
“The FDR is not an active component for safe operation directly but is crucial for accident investigations. It helps recreate the sequence of events leading to an accident, providing invaluable data for understanding what went wrong.” - Crew Communication Issues
The NSIB found that the flight crew used non-standard phraseology throughout the flight. Additionally, there were no standard callouts during various flight phases, a deviation from established aviation protocols. - Technical Faults and Deferred Maintenance
The helicopter’s Radio Altimeter (Rad alt), a critical system that provides altitude information during flight, was flagged as faulty on October 18, just six days before the crash. The issue had been deferred and not resolved before the incident.
Recovery Efforts and Pathological Tests
Five bodies were recovered following the crash, but three remain missing, including the flight crew. Pathological tests, including autopsies, have been conducted on the recovered bodies, and some families have requested DNA testing to confirm identities.
NSIB Director-General, Captain Alex Badeh Jr., clarified that:
“The recovered bodies were handed over to the police for custody. While our role involved taking samples for pathological analysis, the operator is now handling DNA tests for further identification.”
Recommendations for Improved Safety
The NSIB report emphasised the urgent need for stricter compliance with aviation safety regulations to prevent similar tragedies:
- Mandatory Installation of FDRs: The NCAA must enforce compliance with Nig.CARs to ensure that all eligible helicopters are equipped with FDRs. This would enhance the effectiveness of future accident investigations.
- Standardised Communication Protocols: Flight crews should adhere to standard aviation phraseology and callouts to maintain clarity and safety during operations.
- Timely Maintenance: Aircraft operators must address technical faults promptly to ensure optimal functionality of all critical systems.
Lessons from the Incident
The crash has highlighted significant gaps in compliance and operational standards within Nigeria’s aviation sector. Experts believe that addressing these issues could improve safety and reduce the likelihood of future accidents.
Industry Reactions
Stakeholders in Nigeria’s aviation industry have expressed concern over the findings. The NCAA has been urged to take immediate action to strengthen oversight and ensure operators adhere to safety regulations.
The Sikorsky helicopter crash serves as a sobering reminder of the importance of stringent safety measures in the aviation sector. As investigations continue, the NSIB’s recommendations aim to prevent future tragedies and improve Nigeria’s aviation safety record. Ensuring compliance with regulations, fostering transparent maintenance practices, and prioritising crew training will be critical in achieving these goals.
This tragic incident underscores the need for a collective commitment from all stakeholders to prioritise safety and accountability in Nigeria’s aviation industry.
