The United States National Transportation Safety Board (NTSB) has concluded its investigation into the helicopter crash that tragically killed former Access Holdings Plc CEO, Herbert Wigwe, and his family last year.
The crash, which occurred on February 9, 2024, in California near the Nevada border, claimed the lives of Wigwe, his wife Doreen, their son Chizi, and the former group chairman of Nigerian Exchange Group Plc (NGX Group), Abimbola Ogunbanjo.
In the final report, the NTSB stated that the probable cause of the crash was the pilot’s decision to continue the flight under visual flight rules (VFR) into instrument meteorological conditions (IMC).
The NTSB explained that the pilot likely experienced spatial disorientation while manoeuvring the helicopter in poor visibility conditions, leading to the loss of control and a fatal collision with terrain.
The investigation further revealed that the helicopter company’s inadequate oversight of its safety management processes contributed to the incident.
The NTSB found that the helicopter company failed to ensure that its pilots accurately completed and updated flight risk analyses, logged maintenance discrepancies, and adhered to Part 135 regulations before departure. These failures were critical in the chain of events that led to the crash.
