A U.S. safety investigation has determined that the February 2024 helicopter crash that killed Nigerian banking executive Herbert Wigwe, his family, and business associate Abimbola Ogunbanjo resulted from pilot error and equipment failure.
The National Transportation Safety Board (NTSB) found the pilot continued flying under visual flight rules despite deteriorating weather conditions near the California-Nevada border. The aircraft entered instrument meteorological conditions, causing spatial disorientation and loss of control.
Investigators revealed the helicopter’s radar altimeter – which measures altitude – was non-functional before the fatal flight. Maintenance records showed the pilot and maintenance director were aware of the malfunction but proceeded with the journey.
The crash claimed the lives of Wigwe, former Access Holdings CEO; his wife Doreen; son Chizi; and former Nigerian Exchange Group chairman Ogunbanjo. The NTSB report highlights critical safety lapses in the decision to fly with known equipment issues during poor weather conditions.
The findings come 15 months after the tragic incident that shocked Nigeria’s business community and raised questions about aviation safety standards for private charters. Industry experts say the report underscores the importance of strict adherence to maintenance protocols and weather-related flight restrictions.
