Ten people killed in plane crash in Addison, Texas

National Transportation Safety Board Chairman Bruce Landsberg told reporters during a news conference Sunday night that two victims were members of the flight crew and the other eight were passengers on the Beechcraft Super King Air 350 aircraft.

Officials are still trying to determine what caused the plane, that was headed from Addison to St. Petersburg Florida, to go down and say their focus today will be on trying to find perishable evidence.

The identities of the ten victims have not been officially released by the medical examiner, but a church community is in mourning after the loss of their own.

Members of the NTSB arrived on the scene to investigate the crash Sunday and began assessing the damage to the plane immediately, Jennifer Rodi, senior air safety investigator with the NTSB, told reporters.

Landsberg says the plane was cleared for takeoff about a minute before the recording ended. He says crew comments "consistent with confusion" were followed by comments regarding a problem with the left engine.

Separately, the pilot failed to perform a “checklist” and other safety procedures like computing the weight and balance before taking off, the National Transportation Safety Board said.

The lawsuit, which was filed in Dallas County this week, claims the plane was crashed by the negligent operation of the aircraft by defendants EE Operations, EE Realty and S&H Aircraft.
