The Federal Motor Carrier Safety Administration has ordered the immediate shutdown of Scapadas Magicas, the National City company that owns the bus involved in the Feb. 3 crash in Yucaipa that killed eight people and injured 20.
In a statement, the FMCSA said it declared the carrier to be an "imminent hazard to public safety." It said inspectors found "serious mechanical safety violations" during a post-crash investigation.
The agency, which is part of the federal Department of Transportation, ordered Scapadas Magicas to shut down its two remaining motorcoaches operating in the U.S.
The FMCSA inspects motor carriers with the help of local law enforcement agencies. It maintains the data on its website, including a watch list of the bus companies that rack up the most safety violations.
Of the 349 bus companies in California, 62 are on the saftey violation watch list -- including Scapadas Magicas.
According to FMCSA inspection records, the bus that crashed in Yucaipa was cited four times in the last 24 months -- twice in a period of two months for out-of-service brakes.
But on January 9, 2012, the FMCSA gave a satisfactory compliance review -- the highest rating possible -- in a safety audit.
The National Transportation Safety Board is still investigating the crash, with help from the FMCSA and the California Highway Patrol.
