UPDATE- California authorities have lowered the death toll in tour bus crash from 8 to 7.

More on this story:

The bus that crashed on a narrow mountain road near Yucaipa, Calif., on Sunday night, killing at least seven people and injuring more than 30 others, had been cited repeatedly in recent months for poor maintenance.

In October, owner Scapadas Magicas, a small firm in National City, was cited for eight deficiencies found during a roadside check of the vehicle. They included a damaged windshield, lack of a properly installed fire extinguisher and other problems.

In July, the same bus was cited for a damaged windshield, as well as a faulty axle and brakes. In May, its wheel fasteners were loose or missing. 

The violations helped place the company below industry norms for safety. More than 75% of carriers in the same class have a better safety record, according to the U.S. Department of Transportation.
