Six Flags filed in court that it has no liability on the fatal accident of a woman last July aboard the Texas Giant roller coaster.

In response to the lawsuit filed by the family of the Dallas woman who died in the ride, the amusement park denies any liability on the said death since it complied with all the necessary inspections and maintenance procedures recommended by the Gerstlauer Amusement Rides - the German company who designed and built the roller coaster.

Six Flags also said that it is unaware of any similar incidents on the said ride.

"Six Flags believes it met all of the manufacturer's maintenance and operational instructions, applicable to ASTM (American Society of Testing and Materials International) standards and all the requirements of Texas law as evidenced by the fact that the new Texas Giant roller coaster had received a certificate of inspection indicating same from an independent inspector just a few months before the incident involving Mrs. Esparza," according to the recent court filing as quoted by Miami Herald.

Rosa Esparza met her death during her first visit to the Amusement Park. Her family filed a lawsuit against the amusement park, Six Flags Entertainment Corp., Six Flags Theme Parks, Inc. and Texas Flags, Ltd. as defendants. The family is seeking $1 million in damages.

Following the fatal accident, the ride was shut down. It was reopened to public last month after investigation carried out by the amusement park itself concluded that no mechanical error caused the accident. However, the ride was equipped with newly designed restraint-bar pads and seat belts.

According to report citing the filing of the family, "the car had no seat belt or shoulder harness, only a single lap or "T-bar" to restrain passengers."

Furthermore, the family's lawsuit claimed that problems were found on the ride's security system. They said that the green-light system was inconsistent and having intermittent failures and that the train should not have been dispatched until all safety precautions were met.
