Inman said those groups include operations, which will examine flight history and crewmember duties; structures, which will document airframe wreckage and the accident scene; power plants, which will focus on aircraft engines and engine accessories; systems, which will study the electrical, hydraulic and pneumatic components of the two aircraft; air traffic control, which will review flight track surveillance information, including radar, and controller-pilot communications; survival factors, which will analyze the injuries to the crew and passengers and crash and rescue efforts; and a helicopter group.
The NTSB is an independent federal agency responsible for investigating all civil aviation accidents as well as serious incidents in the U.S. involving other modes of transportation, such as railroad disasters and major accidents involving motor vehicles, marine vessels, pipelines and even commercial space operators.
For the investigation into Wednesday's crash, the NTSB will establish several different working groups, each responsible for investigating different areas connected to the accident, board member Todd Inman said.
The investigation also will include a human-performance group that will be a part of the operations, air traffic control and helicopter groups and will study the crew performance and any factors that could be involved such as human error, including fatigue, medications, medical histories, training and workload, Inman said.
National Transportation Safety Board Chairwoman Jennifer Hommendy described the investigation into the crash Wednesday night as an “all-hands-on-deck event” for the agency during a news conference Thursday in which she appeared with members of the board and a senior investigator overseeing the probe.
