The United States National Transportation Safety Board (NTSB) has released its final report on the February 9, 2024, helicopter crash near the California-Nevada border that claimed the lives of six people, including Herbert Wigwe, former Group CEO of Access Holdings Plc, his wife Doreen, their son Chizi, and Abimbola Ogunbanjo, former Group Chairman of the Nigerian Exchange Group Plc (NGX Group).
The report attributes the tragedy to pilot error, specifically spatial disorientation caused by the pilot’s decision to continue a visual flight rules (VFR) flight into instrument meteorological conditions (IMC), compounded by the helicopter company’s inadequate safety oversight and a non-functional radar altimeter.
This devastating incident, which rocked Nigeria’s business community, underscores critical lapses in aviation safety protocols and has reignited calls for stricter regulatory enforcement.
The Crash: A Sequence of Fatal Errors
The Airbus Helicopter EC130B4, registered as N130CZ and operated by Orbic Air, LLC under Part 135 charter regulations, departed Palm Springs, California, at 8:45 p.m. PST on February 9, 2024, en route to Boulder City, Nevada.
The flight followed Interstate 15 but encountered adverse weather—rain and a mix of snow—near Halloran Springs, California, around 10:08 p.m.
The NTSB report, released on May 7, 2025, identifies the probable cause as “the pilot’s decision to continue the visual flight rules flight into instrument meteorological conditions, which resulted in the pilot’s spatial disorientation and loss of control.”
Spatial disorientation, a phenomenon where pilots lose their sense of direction due to poor visibility, led to the pilot’s inability to maintain control, causing the helicopter to crash into high, mountainous desert terrain.
The wreckage, spanning a 100-yard debris field, showed catastrophic damage, with fragmented fuselage, destroyed cockpit, and thermally damaged components, indicating the force of the collision.
Eyewitnesses reported a “fireball” along Interstate 15, prompting emergency calls, and law enforcement confirmed the crash site’s remote, scrub-covered location.
Pilot Error: A Fatal Misjudgment
The NTSB’s investigation highlights the pilot’s critical error in continuing the VFR flight into IMC, which required instrument flight rules (IFR) protocols and specialized training.
The preliminary report, issued in February 2024, noted that the helicopter was operating under VFR but encountered conditions—low visibility due to rain and snow—that demanded IFR navigation.
The pilot, likely disoriented by the lack of visual cues, experienced vestibular illusions, such as “the leans” or somatogravic illusion, where the body misinterprets motion, as seen in prior crashes like the 2020 Kobe Bryant incident.
The pilot’s decision-making was further compromised by inadequate communication. During an earlier positioning flight, the pilot texted the director of maintenance (DOM) about a malfunctioning radar altimeter, a critical instrument for low-altitude navigation.
A company mechanic attempted troubleshooting but failed to resolve the issue, and both the pilot and DOM were aware the altimeter remained non-functional.
Despite this, the helicopter departed at 6:22 p.m. to pick up passengers, and after landing, the pilot and a flight follower (also the company president) exchanged messages but failed to discuss the altimeter’s status or worsening weather conditions.
This omission, the NTSB notes, reflects a breakdown in situational awareness and risk assessment.
Company Negligence: Systemic Safety Failures
The NTSB report sharply criticizes Orbic Air, LLC for “inadequate oversight of its safety management processes,” a contributing factor to the crash.
The company failed to ensure pilots accurately completed and updated flight risk analyses, logged maintenance discrepancies, and adhered to Part 135 regulations, which govern charter operations.
These lapses allowed the flight to proceed despite known mechanical issues and deteriorating weather. The non-functional radar altimeter, unaddressed before departure, likely exacerbated the pilot’s challenges in IMC, as it could have provided critical altitude data.
The NTSB’s findings echo systemic issues identified in other high-profile crashes, such as the 2020 Kobe Bryant case, where Island Express Helicopters’ inadequate safety management contributed to a similar VFR-into-IMC accident.
Orbic Air’s failure to enforce rigorous pre-flight protocols, including weather briefings and maintenance checks, underscores a broader need for enhanced safety management systems (SMS) in Part 135 operations, as recommended by the NTSB in prior reports.
The Victims: A Profound Loss
The crash claimed the lives of all six aboard: Herbert Wigwe, 57, a titan of Nigerian banking; his wife Doreen; their son Chizi; Abimbola Ogunbanjo, a prominent figure in Nigeria’s financial sector; and two crew members, the pilot and safety pilot.
Wigwe’s death, in particular, sent shockwaves through Nigeria, with President Bola Tinubu, Lagos Governor Babajide Sanwo-Olu, and former Vice President Yemi Osinbajo mourning his loss as a “colossal” blow to the nation’s economy.
Access Holdings called it a “major loss,” while the Nigerian business community continues to grapple with the void left by Wigwe and Ogunbanjo.
Investigation and Broader Implications
The NTSB, in collaboration with the Nigerian Safety Investigation Bureau (NSIB) and France’s Bureau of Enquiry and Analysis for Civil Aviation Safety (BEA), conducted a 15-month investigation, led by investigators Aaron Sauer and Mark Ward.
The probe included aerial drone mapping, debris analysis, and reviews of pilot records, maintenance logs, and ADS-B flight data, which showed the helicopter veering off course with increasing ground speed before a rapid descent.
The NSIB’s involvement, under Director-General Alex Badeh, ensured Nigeria’s participation due to the victims’ significance, per international aviation protocols.
Public sentiment on X reflects grief and frustration, with posts like @Naija_PR and @SaharaReporters emphasizing pilot error and company negligence, while @MobilePunch called for accountability in aviation safety.
The crash has renewed scrutiny of Part 135 operators, with experts urging the FAA to mandate SMS programs and advanced training for IMC scenarios, as recommended post-Bryant crash.
What you should know
The Wigwe crash highlights persistent risks in helicopter charter operations, particularly VFR flights in marginal weather.
The NTSB’s findings point to the need for stricter oversight, mandatory IFR certification for Part 135 pilots, and robust SMS implementation.
Technologies like crash-resistant flight recorders, absent in the EC130B4, could have provided critical data, as noted in prior NTSB recommendations.
The non-functional radar altimeter, a preventable issue, underscores the urgency of rigorous maintenance protocols.
For Nigeria, the loss of Wigwe and Ogunbanjo is a stark reminder of the global stakes in aviation safety.
As legal battles over Wigwe’s estate continue and Nigeria mourns, the NTSB’s report serves as a call to action to prevent future tragedies.
The question remains whether the FAA and operators like Orbic Air will heed these lessons to ensure no family endures such a loss again.
