KMG, the maker of the Fire Ball, said its investigation found that excessive corrosion led to the accident that killed Tyler Jarrell at the Ohio State Fair last month.
The statement, posted to KMG Europe's Facebook page, said corrosion on the interior of the support beam reduced the beam's thickness and that's what led to the accident at the Ohio State Fair.
KMG's statement said the investigation involved a review of video footage and a metallurgical inspection of the ride. That's when they found the corrosion that had built up in the 18 years the ride had been active.
The accident on fair opening day killed 18-year-old Jarrell and injured seven more people.
