Knott's Berry Farm is facing continued delays in its efforts to reopen the Xcelerator rollercoaster, with investigators yet to finalize a report on the incident last year which forced its closure.
California's Division of Occupational Safety and Health is leading the investigation into the incident last September, which saw two riders injured when a launch cable snapped. The Orange County Register reports that the state investigators' report is awaiting "final approval" from supervisors, with no target date set for its completion.
Knott's Berry Farm is powerless to reopen the ride until the report is released and investigators confirm that they are satisfied with safety upgrades made following the incident. The park's website currently lists April 30 as the planned reopening date, but this date has repeatedly been moved back as the investigation drags on.
The incident on September 18, 2009 saw two riders injured when a cable snapped, showering them with debris. The cause is believed to have been a serious malfunction in Xcelerator's hydraulic launch system, which catapults the coaster towards a top speed of 82mph. The cable - which is part of the launch system - reportedly snapped, creating a cloud of debris and striking a 12-year-old boy in the leg. The injured boy was taken to hospital for treatment along with a male adult rider who suffered back and neck injuries. Both riders' injuries were said to be mild-to-moderate in nature.
The Xcelerator incident was a blow to Intamin AG, one of the world's leading coaster designers. Another hydraulically-launched coaster designed by AG, Top Thrill Dragster at Cedar Point, suffered a similar incident in 2004. On that occasion, a snapped launch cable led to metal shards and hot oil being sprayed onto riders.
