The wreckage of Asiana Flight 214, a Boeing 777 airliner, is seen after it crashed at the San Francisco International Airport Saturday.
A Chicago law firm says it plans to sue aircraft manufacturer Boeing Co. on behalf of 83 people who were on the Asiana Airlines flight that crash-landed in San Francisco.
Ribbeck Law Chartered says in a news release that it filed a petition Tuesday in Cook County Circuit Court in Chicago to help preserve evidence in the July 6 crash. Three people were killed when the Boeing 777 clipped a seawall at the end of a runway.
Ribbeck says additional pleadings will be filed against Asiana Airlines and several component parts manufacturers.
The firm says the crash of Asiana Flight 214 might have been caused by a mechanical malfunction of the auto-throttle. It also says some sliding ramps reportedly opened inside the plane, injuring passengers and blocking their exit.
On-scene investigation concludes
The National Transportation Safety Board officially closed its San Francisco command post on Monday, concluding the on-scene investigation into the crash-landing.
The NTSB said in a statement Monday that its investigative team has completed the examination of the airplane wreckage and runway at San Francisco International Airport.
The wreckage will still be available for further examination if necessary at a secure storage location at the airport.
Investigators completed several witness interviews over the weekend and were expected to finish interviewing first responders Monday.
The agency says the next phase of the investigation will include additional interviews, examination of the evacuation slides and other airplane components, and more in-depth analysis of the airplane's performance.
NTSB: "Appropriate action" taken after name flap
A spokeswoman for the National Transportation Safety Board says "appropriate action" has been taken after a summer intern confirmed erroneous and racially offensive names for the pilots of Asiana Flight 214.
An anchor for KTVU-TV read the names on the air Friday before apologizing for the error after a break. The NTSB says the intern erroneously confirmed the names "outside the scope of his authority."
Asiana says the TV report "badly damaged" the reputation of the airline and its pilots, and plans to sue the station.
NTSB spokeswoman Kelly Nantel says the agency does not discuss specific personnel matters but has taken "appropriate action to deal with the situation." She says interns in the agency's office of public affairs are unpaid.
