The United States National Transportation Safety Board has attributed the helicopter crash that killed former Access Holdings CEO, Herbert Wigwe, his wife, son, and three others to pilot error caused by spatial disorientation. 

The NTSB report, released today, further indicted the helicopter company, accusing it of inadequate oversight of its safety management processes. Preliminary report earlier showed that the helicopter crashed while operating under visual flight rules in what ultimately became instrument meteorological conditions, requiring different flight protocols and instrumentation. The US accident investigators further revealed that the helicopter company failed to ensure pilots properly completed flight risk analyses, recorded maintenance issues, and followed required regulations before departure. 

The crash, which occurred near the California-Nevada border on 9 February 2024, claimed the lives of all six people on board, including Wigwe, his wife Doreen, their son Chizi, and Abimbola Ogunbanjo, former group chairman of Nigerian Exchange Group Plc
