Officials say two people were killed Thursday, August 6, 2025, when a helicopter struck a power line and crashed onto a barge on the Mississippi River. The crash occurred near the Missouri–Illinois border by Alton/West Alton. The FAA reported the impact occurred at approximately 11:05 a.m. near the Alton Dam area.
Investigators said the flight involved work on transmission lines over the river, including installation or maintenance of orange aerial-marker balls and tower lighting. On Friday, the NTSB identified the helicopter as a 1976 Hughes 369D. FAA records indicate the helicopter as registered to Excel Helicopters of Salem, Missouri. J.F. Electric stated that one of its employees and a subcontractor were among the two people who died, and Ameren confirmed contractors were performing repairs and replacing marker balls and lighting in Madison County at the time.
The FAA and NTSB are leading the investigation. Identities of the victims have not yet been released pending notification of next of kin.
Potential Causes and Contributing Factors
Investigators will look broadly at the circumstances and equipment involved. In wire-strike events, common avenues of inquiry include:
- Wire-strike hazards and visibility: Investigators examine line marking and patrol procedures, including the known dangers of power lines for low-altitude operations.
- Aircraft systems and upkeep: Maintenance history, component condition, and any prior discrepancies may be reviewed, along with whether any issues raise product liability concerns.
- Operational planning: Route selection, altitude, and communications in a complex river and industrial corridor.
- Recorded data: Availability of cockpit audio, tracking, and flight data from avionics or onboard devices that can help reconstruct the final minutes.
Risks and Safety Considerations
Wire-strike helicopter crashes can lead to burns, orthopedic trauma, and serious and catastrophic injuries for survivors. Beyond immediate medical needs, families confront funeral costs, lost income, and long-term recovery needs. In similar incidents, claims may involve multiple parties, including operators, contractors, utilities, or parts manufacturers, depending on what the evidence shows.
Legal Rights and Options
Victims and families may have the right to bring a wrongful death claim. Recoverable damages can include economic damages (medical bills, lost earnings) and non-economic damages (pain, mental anguish, loss of companionship). Aviation cases often require careful coordination with federal investigators and timely preservation of maintenance records and operational data. All claims must be brought within the applicable statute of limitations.
If you are dealing with the aftermath of a helicopter crash, working with an aviation accident attorney or helicopter crash attorney can help identify responsible parties and protect your rights.
Frequently Asked Questions
How long until preliminary findings are public?
The NTSB typically releases a preliminary report within about two weeks. It is factual only and does not assign blame.
What if maintenance or a part failure is suspected?
Your counsel can pursue a product liability theory if component defects or warnings issues emerge.
Do families have to wait for the final NTSB report to act?
No. Civil cases often begin while the investigation proceeds, with careful attention to preserving evidence and meeting filing deadlines under the statute of limitations.
