2009 Knott's Berry Farm Roller Coaster Accident Caused by Improper Maintenance, Say California Investigators
According to a Cal/OSHA investigation, the 2009 Orange County, California roller coaster accident at Knott's Berry Farm that hurt two people was preventable. Citing improper maintenance, the investigation places the blame on Intamin AG, the Xcelerator's manufacturer, and the amusement park.
The incident occurred on September 16, 2009. An on-board video camera of the Buena Park accident shows the cable snapping loose while debris sprays the riders. The cable cut a 12-year-old boy on the leg while an adult male sustained back injuries.
Cal/OSHA said that Intamin AG's ride maintenance instructions were "confusing" and not clear on whether the roller coaster cable needed to be checked every six months or once a month. While the manufacturer intended that the examination should take place once a month, the amusement park was checking it twice a year. The state blames Knott's for being more than two weeks overdue on its six-month cable inspection when the Buena Park roller coater accident happened.
The Xcelerator, which was shut down after the Orange County, California amusement park accident happened, reopened last week. Per the California Division of Occupational Safety and Health's requirements, Knott's has added additional safeguards to the hydraulic launch accelerator coaster. Knott's and Intamin will work together to modify the maintenance instructions.
This is not the first time Intamin and Knott's have been involved in roller coaster accidents. In 2004, metal debris from a launch cable also struck passengers on the Top Thrill Dragster at Cedar Point in Ohio, Knott's sister park. Intamin was also the manufacturer of that roller coaster. In 2001, a woman died at the amusement park after falling from Perilous Plunge water ride, which was also made by Intamin.
Amusement Park Accidents
Unfortunately, amusement park rides can deliver more than just fast thrills and laughter. In the event that a ride malfunctions, injuries can result, ranging from bloody noses to bank injuries, broken bones, severed limbs, spinal cord injuries, traumatic brain injuries, and even death.
The competition to build and run the highest and fastest rides should not compromise rider safety. You may have grounds for filing a California products liability case against a negligent ride manufacturer and/or an amusement accident lawsuit against the thrill park.
