U.S. officials are investigating why a Southwest Airlines jet blew two tires during an aborted takeoff in Sacramento, Calif.
Federal Aviation Administration spokesman Ian Gregor said Thursday that the agency hasn't determined the cause of Tuesday night's incident.
Southwest is also in the process of investigating the event. In a statement from Southwest, Whitney Eichinger said the following:
"Tires are part of Southwest's FAA approved Continuing Airworthiness Maintenance Program, and are routinely and repetitively checked to ensure their integrity. Even so, there are occasions when tires do fail as a result of atypical conditions."
There were 130 passengers aboard the Seattle-bound 737. No one was injured. Officials closed the runway at Sacramento International Airport but reopened it on Wednesday.
Tires on jetliners can blow out after hitting debris on the runway, from problems with the plane or the tires, or from heavy braking.
Southwest towed the plane off the runway and took it out of service.
